ci: fix texlive.svg viewBox and add icon paths to CI go filter (#24322)

## What

Fixes the `TestSVGIconAttributes/texlive.svg` CI failure introduced by
#24312.

Two changes:

1. **Fix `texlive.svg` viewBox**: Changed from `0 0 1024 1024` to `0 0
256 256` (wrapping content in `<g transform="scale(0.25)">` to preserve
rendering). Also cleaned up non-standard attributes (`version`, `style`,
`preserveAspectRatio`) to match other icons.

2. **Add icon/theme paths to CI go filter**: Added `site/static/icon/**`
and `site/src/theme/**` to the `go` path filter in `ci.yaml` so Go tests
(`test-go-pg`, `test-go-pg-17`, `test-go-race-pg`) run when icons or
theme config change. This is why the failure wasn't caught on the PR —
only `site/` files were modified, so Go tests were skipped entirely.
