Fix relrefs for .md files in redisvl latest release

[paoloredis]

Note

Medium Risk
Changes the docs sync workflow’s link-rewrite rules, which could affect many generated pages if the new regexes mis-handle edge cases or anchors.

Overview
Updates the redisvl_docs_sync GitHub Actions workflow to rewrite intra-doc *.md links into Hugo relref shortcodes during the markdown formatting step, including support for stripping numeric filename prefixes (e.g. 01_) and handling both path-based and same-directory links.

This reduces broken navigation in the generated RedisVL “latest” docs by ensuring cross-page links resolve correctly after files are renamed/organized for Hugo.

This change fixes relrefs for the concepts content, e.g. the links at the bottom of this page https://redis.io/docs/latest/develop/ai/redisvl/concepts/architecture/

@paoloredis The regexes don't seem to be quite right. For example, when I click the link to Search & Indexing at the bottom of the Architecture page, the URL is

https://redis.io/docs/staging/DOC-6504/develop/ai/redisvl/concepts/architecture/search-and-indexing.md

...which gives a 404. The actual link should be

https://redis.io/docs/staging/DOC-6504/develop/ai/redisvl/concepts/search-and-indexing

(ie, no architecture folder in the path and no .md suffix on the file name.) The staging build does seem to have completed, so I don't think it's just a stale file.

[paoloredis]

Yeah, that's expected. Right now the redisvl workflow isn't running as part of staging builds so pages won't be updated

[andy-stark-redis]

OK, then - approved.
