QA pass on varFreqs per-subtrack description pages: encode 3 plain emails, add target=_blank to 15 boilerplate REST API links, and add missing References sections (and Data Access on varFreqsAll). refs #36642

Mechanical fixes across 18 per-subtrack description pages:
- Encoded 3 plain author/contact emails: pfeliciano@simonsfoundation.org (sfariSparkExomes), m.hobbs@garvan.org.au (mgrb), contact_npco@a-star.edu.sg (npm).
- Added target="_blank" to 15 occurrences of the boilerplate "<a href=https://api.genome.ucsc.edu>REST API</a>" link across allofus, topmed, sfariSparkExomes, tommo60kjpn, alfaVcf, gasp, abraom, indigenomes, hrc, saudi, schema, sgdpFreq, gregor, hgdp1kFreq, colorsDbSnv.

Added missing References sections:
- allofus.html: All of Us Research Program 2024 Nature.
- topmed.html: Taliun 2021 Nature.
- alfaVcf.html: NCBI ALFA documentation citation (no peer-reviewed paper yet).
- gregor.html: GREGoR R04 Methods document + consortium website (no flagship publication yet).
- varFreqsAll.html: pointer to the supertrack's References section, plus tool citations (bcftools csq, Ensembl VEP).

Added missing Data Access section on varFreqsAll.html explaining that the merged callset is not downloadable due to mixed source-data licensing, but can be reconstructed from the per-subtrack VCFs using the conversion scripts on GitHub.

All 25 unique varFreqs description pages now have Description, Methods, Data Access, References. No non-ASCII characters and no inline event handlers across the set.

 <h2>Description</h2>
 <p>
 <a href="https://clingen.igib.res.in/indigen/" target="_blank">IndiGenomes</a> provides
 whole genome sequencing data of 1,029 healthy Indian individuals under the pilot phase of the
 &quot;IndiGen&quot; program. Only the allele frequency is available from this project. The website
 also provides SV call and Alu insertion VCFs.

 <h2>Data Access</h2>

 The data can be explored interactively with the

 <h2>Methods</h2>
 <p>
 Genomic DNA was extracted from 5 ml of peripheral blood collected via venipuncture from
 1,029 self-declared healthy Indian individuals representing diverse geographic, ethnic, and
 linguistic groups, using the salting-out method. Whole-genome libraries were prepared using
 the TruSeq DNA PCR-free library preparation kit (Illumina). Sequencing was performed on the
 Illumina NovaSeq 6000 platform with 150&times;2 bp paired-end reads targeting &ge;30&times;
 mean coverage. Alignment to the GRCh38 reference genome, post-processing, and
 default quality-filtered variant calling were performed end-to-end on the Illumina DRAGEN
 v3.4 Bio-IT platform, which uses field-programmable gate array (FPGA) logic for
 high-throughput processing. This yielded a compendium of 55,898,122 single allelic
 genetic variants (SNVs and indels), of which 32.23% were unique to the Indian samples
 and absent from global reference databases. Variants were annotated using ANNOVAR with
 RefGene, and allele frequencies were cross-referenced against gnomAD v3, 1000 Genomes,
 ExAC, ESP6500, and the Greater Middle East Variome Project. The dataset is accessible via
 the <a href="https://clingen.igib.res.in/indigen/" target="_blank">IndiGenomes database</a>

 We provide documentation that indicates how all source files of the varFreqs track were converted in the <a href="https://github.com/ucscGenomeBrowser/kent/blob/master/src/hg/makeDb/doc/hg38/varFreqs.txt" target="_blank">makeDoc file</a> of the track.
 For some tracks, python scripts were necessary and are also available from <a href="https://github.com/ucscGenomeBrowser/kent/blob/master/src/hg/makeDb/scripts/varFreqs" target="_blank">GitHub</a>.
