feat(claude-code-settings): allow git marketplace URLs without .git suffix

[esp0]

Summary

extraKnownMarketplaces and blockedMarketplaces constrain the git source's url field with a \.git$ pattern. This rejects valid marketplace URLs from git hosts that don't use a .git suffix, such as Azure DevOps (https://dev.azure.com/org/project/_git/repo) and AWS CodeCommit.

Per the official docs (Create and distribute a plugin marketplace):

Full git repository URL (https:// or git@). The .git suffix is optional, so Azure DevOps and AWS CodeCommit URLs without the suffix work

• Removed the \.git$ pattern from both extraKnownMarketplaces and blockedMarketplaces's git source url field. This also brings them in line with strictKnownMarketplaces, which already has no such pattern on its equivalent field.
• Added the documentation anchor link to both url field descriptions, per CONTRIBUTING.md's convention of using <description>\n<url>.
• Added positive test coverage (Azure DevOps URLs) to marketplace-host-pattern.json and managed-settings.json.
• Removed two negative test fixtures that asserted "missing .git suffix is invalid" — that assumption no longer holds per the docs, and keeping them would fail Ajv's negative-test validation now that the pattern is gone.

Test plan

• node ./cli.js check --schema-name=claude-code-settings.json passes
• node ./cli.js coverage --schema-name=claude-code-settings.json passes (8/8, strict mode)

Heads-up: I've included this change in my v2.1.251 sync PR (#6273), with credit to you.

I deferred to this PR in my previous sync (#6131) rather than duplicating it, but since it's been sitting a while I folded it in so the fix isn't waiting on mine. Your test fixtures and the two negative-test removals are carried over as-is. If this one merges first, the overlap is harmless — the change is identical.

For what it's worth, I re-verified it against plugin-marketplaces#git-repositories: "The .git suffix is optional, so Azure DevOps and AWS CodeCommit URLs without the suffix work." strictKnownMarketplaces's git variant already had no .git$ pattern, so the schema was inconsistent with itself.
