[DOCS] Plugin marketplace docs incorrectly require `.git` suffix for git URLs

Documentation Type

Incorrect/outdated documentation

Documentation Location

https://code.claude.com/docs/en/plugin-marketplaces

Section/Topic

Git URL source requirements for plugin marketplace/plugin source configuration.

Current Documentation

The plugin source schema currently states:

| url | object | url (must end .git), ref?, sha? | Git URL source |

And later:

| url | string | Required. Full git repository URL (must end with .git) |

What's Wrong or Missing?

Release v2.1.72 added support for marketplace git URLs without a .git suffix (including Azure DevOps and AWS CodeCommit patterns).

Current docs still state .git is required, which is now outdated and can cause users to incorrectly reject valid URLs or rewrite URLs unnecessarily.

Suggested Improvement

Update plugin marketplace docs to reflect current behavior:

1. Change requirement language from "must end with .git" to ".git optional".
2. Add examples without .git (including Azure DevOps and AWS CodeCommit-style URLs).
3. Keep compatibility note that existing .git URLs remain valid.

Impact

Medium - Makes feature difficult to understand
