docs: Remove unnecessary ST_SRID in example queries

[yutannihilation]

After #275 and #449, ST_GeomFromText and ST_Point accepts SRID as the last argument. So, in theory, we can replace the following ST_SetSrid() usages.

• ST_SetSrid(ST_GeomFromText('wkt'), srid) -> ST_GeomFromText('wkt', srid)
• ST_SetSrid(ST_Point(x, y), srid) -> ST_Point(x, y, srid)

The R failures are very strange:

[ FAIL 3 | WARN 0 | SKIP 0 | PASS 81 ]

On my local checkout all the tests pass if I step through the file, but if I run with devtools::test() I get the two failures and I can't get the lintr test to fail locally. I'll try to circle back to this at some point today.

I think I found the first one, which is apache/datafusion#18201. This will be resolved when we update to DataFusion 52 (which will happen some time after we release SedonaDB 0.3). If the lintr error is still here I (or you) can add skip_on_ci() to the lintr test or nolint start: indentation_linter / nolint end around the offending lines.

Oh, thanks so much for investigating and fixing! I was stuck as I had no idea what was happening here.
