Updates CLI messages for namespace storage limits

What does this MR do and why?

This MR updates CLI messages for namespace storage limits to include updated/new URLs to our docs, namely:

• Updating the usage quotas anchor from #manage-your-storage-usage to #manage-storage-usage
• Adds some additional info URLs to the message when a git push would take a customer over their limit (scenario 2 below)

The messages are all different and are displayed in various scenarios (screenshots below):

1. git push to a project in a namespace that is approaching their storage limit
2. git push to a project that would take it over their storage limit
3. git push to a project that is already over their storage limit

These messages are all behind various application settings and feature flags, which are currently disabled, hence no changelog.
