Spell the acronym PCLAI, not pcLAI. refs #35415

The authors write it PCLAI throughout: the upstream README at
AI-sandbox/hprc-pclai uses PCLAI 18 times and pcLAI never, under the title
"Point Cloud Local Ancestry Inference (PCLAI)". We had pcLAI in 517 places,
across the track labels, both description pages, the makedocs, the build scripts
and the autoSql.

hprcPclai.ra holds 467 of those, in shortLabel, longLabel, dataVersion and
comments. It is generated, so the fix went into hprcPclaiMakeTrackDb.py and the
file was rebuilt; every line of the resulting diff differs only by the rename.

Track names, file names and the lowercase pclai in URLs and data file names are
untouched. None of them contained the string pcLAI, and renaming the tracks would
break saved sessions for no user-visible gain.

 That table is turned into the compact JSON the hgc.scatterPlot.js module reads,
 which the pclai track points at with its detailsScript.scatterPlot setting.
 
 Population names are held in a separate list and referenced by index, because the
 descriptors are long and repeat across thousands of haplotypes; each point also
 carries its own haplotype id, which hgc.scatterPlot.js shows on mouseover.
