The button that resets the remote repository input doesn't actually reset the repository

Right now, if the user clicks that button, the input text is reset back to "bluerobotics/blueos-core", but nothing else happens, and it is unclear to the user that the reset click does not fetch the repository that it just reset to.

To actually reset, performing a fetch, the user actually has to click the input box after that and click the enter key of the keyboard, as a "fetch" button also doesn't exist.

Start at the remote repository input's reset button and the existing fetch-on-enter behavior. Verify how reset changes the displayed repository and whether it triggers fetching; done means clicking reset both restores the default repository and fetches it without requiring an extra input or Enter key action.
