easy way to copy commit hashes in front-end

[KiaraGrouwstra]

Is your feature request related to a problem? Please describe.

trying to find a working cached nixpkgs revision, i would try and find an (ideally full) commit hash to copy from the evaluation list or detail views.
from what i can find however, the detail view currently seems not to contain this information, whereas in the list view it seems this info:

1. is limited to a shortened hash
2. with no easy way to copy
3. and in fact, attempts to copy it mostly trigger a navigation to the detail view

Describe the solution you'd like

easy ways to view (and select/copy) commit hashes from both evaluations list and detail views.

Describe alternatives you've considered

1. try and visually select visual hash on evaluation list view
2. try and press copy keybind before releasing mouse press
3. hope this worked before i release the mouse and the click triggers navigation to the evaluation detail view
4. find myself having been navigated to the detail view against my will
5. try and somehow find a hash there
6. fail to find one for some reason

Additional context

maybe i'm just bad at computers idk
