### Amplify Hosting feature

Git providers

### Is your feature request related to a problem? Please describe:

When you have many organizations connected to amplify through github, some repositories are not shown on the select repository drop down list.

I had to delete multiple connections to be able to see the repository I had connected.

Currently i have more than 100 repositories through multiple github organizations connected to amplify.

### Describe how you'd like this feature to work

The dropdown list should show the repositories

Start by reproducing the GitHub-provider repository selection flow with more than 100 repositories across multiple organizations. Trace how the repository dropdown loads and filters entries, then verify that all connected repositories are displayed after the change.
