"No repositories found" is shown when typing a partial repository name in the Add from Repository search field

Steps to reproduce:

1. Open Unity Hub
2. In the Projects tab, click Add > Add from repository
3. Select Gitub or GitLab as Source control provider and Authorize token
4. Make sure there are multiple Repositories available with similar names (e.g. my-project (1), my-project(2))
5. Select one of those repositories in the dropdown
6. Delete half of the repository name (e.g. reduce "my-project" to "my-proj")
7. Observe the repository search results

Actual results: "No repositories found" is displayed despite repositories
matching the partial string existing

Expected results: The search field should query and return all repositories that match the partial string as the user edits it, consistent with standard  search behavior

Reproducible with versions: 3.17.2

Tested on (OS): macOS 26.4, Ubuntu 24.04

Notes:

• Reproduces with both GitHub and GitLab providers
  • On GitHub, the issue is less apparent when the search string does not begin with the username
  • On GitLab, the issue reproduces under all circumstances
• Results only update correctly once a full matching word is entered.
