Allow git repo search when user has many repos

[vincent-psarga]

Description

Currently, we only query the first page of the available GIT repo. When a user has access to many repositories (eg: when they belong to multiple open-source organizations), it may be impossible to find a specific repository.

Steps to Reproduce

1. Have access to more than 100 repositories
2. Try to add the last repository (based on alphabetical order)
3. Cry

Expected Behavior

There is a search field when adding a repository, it would be nice if it was really querying the git provider to find the matching repositories instead of the ones currently displayed.
Or maybe have the possibility to say "Load more"

Actual Behavior

Environment

• Packmind version:
• packmind-cli version (if relevant):
• Browser/OS (if frontend issue):
• Environment (open-source/cloud/on-prem):
