chore(coderabbit): flip request_changes_workflow → false (advisory posture)

[ANcpLua]

Summary

Aligns NET.Sdk's CodeRabbit posture with the other 3 framework repos
(Analyzers, Roslyn.Utilities, Agents): CodeRabbit posts comments rather
than "Request Changes" reviews, so its feedback never blocks GitHub
native auto-merge.

Why

CodeRabbit's "Request Changes" reviews block native auto-merge even
with 0 required approvals on branch protection (GitHub-wide behavior).
On a Renovate or owner PR opened while no human is around to dismiss or
address the review, that means the PR sits indefinitely.

The other 3 framework repos already flipped this (Agents commit
bc06b2e); NET.Sdk was missed. Folding the fix in now since the
follow-on auto-merge PR (#149) already squash-merged before I could
amend it onto that branch.

Test plan

• Diff is the single-line config flip
• CI passes
• Future CodeRabbit review on this repo posts a Comment, not a
  Request Changes — verifiable on the next Renovate PR

Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• .coderabbit.yaml is excluded by none and included by none

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.
