Strip the version from Markdown self-links in versioned builds

[EliShteinman]

Fixes #4060.

Problem

Since DOC-7086 converted RDI 1.19.1's archive to render-hook Markdown links, every link in that archive to another page of the same archive renders on redis.io as a literal href="/content/integrate/redis-data-integration/1.19.1/....md", which 404s. #4060 has examples.

The versioned build jobs strip the version from relref self-links before they move the version up one level and delete its directory. They don't strip it from ](/content/<product>/<version>/...) links, which then point at a page that no longer exists.

Change

In .github/workflows/main.yml, each of the four versioned jobs gets a second gsub in its existing awk (build_kubernetes, build_rs, build_rdi, build_redisvl). The new gsub rewrites ](/content/<product>/<version>/ to ](/content/<product>/, mirroring the one for relref.

Only the RDI archive has Markdown self-links today. The other three jobs get the same line so they don't break when their archives are converted.

Verification

• All archives, three awks: Each of the four awk lines, exactly as written in the workflow, was run under awk (BWK), mawk (the ubuntu-latest default), and gawk. It ran against every archived version on main: 44 versions across the four products.
  • Afterwards, no version-prefixed self-link of either form is left.
  • RDI 1.19.1: 335 Markdown self-links go to 0.
  • The other archives have no Markdown self-links, so the new gsub doesn't change them.
• Real version build: A sandboxed Hugo build of RDI 1.19.1 went through the same steps as the job: remove the other versions, run awk, run rsync --delete-after, run hugo.
  • With the current awk, the version's output had 44 href="/content/ links, from the DOC-7086 installation unit alone.
  • With the fix, it had 0.
  • RS 8.0, RS 7.4, Kubernetes 8.0.18, and RedisVL 0.27.1 had 0 with the fix too.

Note

Low Risk
CI-only preprocessing in the docs workflow; no runtime or auth changes, and the new rewrite mirrors an existing relref step.

Overview
Fixes broken internal links in versioned Hugo doc builds (Kubernetes, RS, RDI, RedisVL) where archived content uses render-hook Markdown paths like ](/content/.../<version>/...).

Each versioned job in .github/workflows/main.yml already rewrites relref shortlinks to drop the version segment before rsync flattens the version directory. This PR adds a matching awk gsub on the same pass so ](/content/<product>/<version>/ becomes ](/content/<product>/, in line with the existing relref behavior.

Comments in those four jobs are updated to note that both relrefs and Markdown links are normalized. RDI 1.19.1 is the archive that currently hits this (335 self-links); the other three products get the same rule so future archive conversions do not regress.
