## PR-Codex overview
This PR modifies the `href` attribute of a `Link` component in the `TeamSelectionUI.tsx` file to ensure that the URL is correctly updated when navigating between teams, specifically when on the `/team` page.

### Detailed summary
- Updated the `href` logic in the `Link` component.
- Added a condition to check if `pathname` starts with `/team`.
- Changed the replacement logic to include the `/team/` prefix for both `currentTeam` and `team`.
