Remove US Government connector List links Fixes #82

The PR will fix issue: #82

The US Gov connector list links in the README are no longer valid. Please remove this sections since the links are not publicly available anymore.

Thanks for the PR! However, these connector list links are actually valid — they require authentication with valid credentials for the respective US Government cloud region (GCC, GCC High, or DoD). They aren't publicly accessible by design, since these are government cloud environments.

Rather than removing these sections, I think the better fix is to add clarifying language noting that the links require authentication. Something like:

Note: The connector list links below require authentication with a valid account in the corresponding government cloud tenant (GCC, GCC High, or DoD). They are not publicly accessible.

This keeps the links available for users who do have access while setting proper expectations for everyone else. I'll put up an alternative PR with this approach.

Thanks for flagging this! These links are actually valid - they just require authentication with a valid tenant account for the respective US Government cloud region (GCC, GCC High, or DoD). They aren't publicly accessible, which is by design for government cloud environments.

Rather than removing the sections, I'd suggest keeping the links and adding a note clarifying the authentication requirement. I've left suggestions on each section below.
