[https://nvbugs/6633929][fix] Fix XGrammar structural tag doc links and pin the source link

[nv-guomingz]

Description

Supersedes #18016 (its two commits are included), addressing the review feedback on top:

• Repoint the three structural-tag tutorial links from the removed https://xgrammar.mlc.ai/docs/structural_tag/structural_tag_api.html (404) to the live https://xgrammar.mlc.ai/docs/latest/structural_tag/structural_tag.html, and remove the now-unneeded test_doc.py::test_url_validity waiver. (from [https://nvbugs/6633929][fix] Repoint all three links to the live versioned page and remove the now-unneeded… #18016)
• Pin the XGrammar backend source link to the shipped version: v0.1.21 -> v0.1.32, matching xgrammar==0.1.32 in requirements.txt. The old anchor matcher.py#L341-L350 no longer marked anything relevant even at v0.1.21; the link now targets compiler.py#L144-L290, the GrammarCompiler methods for JSON schema, regex, structural tag and EBNF.
• The tutorial links stay on /docs/latest/ because XGrammar publishes no versioned doc paths (/docs/v0.1.32/ and /docs/0.1.32/ both 404; verified).

Verification

All three URL forms verified with curl: new tutorial link and the v0.1.32 compiler.py link return 200; the versioned doc-path variants 404.

Dev Engineer Review

• Updated structural-tag tutorial links to the live /docs/latest/structural_tag/structural_tag.html path.
• Updated the XGrammar source link to xgrammar==0.1.32 and compiler.py#L144-L290.
• Removed the obsolete test_doc.py::test_url_validity waiver.
• The changes are limited to documentation links and one test-list entry.
• The link updates are consistent with the documented XGrammar version and verified HTTP 200 responses.

QA Engineer Review

• Removed test_doc.py::test_url_validity from tests/integration/test_lists/waives.txt.
• No test-db/ or qa/ files were modified.
• The test-list format remains valid, and the removed entry is no longer waived.
• Verdict: needs follow-up because CBTS coverage data is unavailable.
