Hide the "Details" link of commit status when the user cannot access actions (#30156)

Fix #26685

If a commit status comes from Gitea Actions and the user cannot access
the repo's actions unit (the user does not have the permission or the
actions unit is disabled), a 404 page will occur after clicking the
"Details" link. We should hide the "Details" link in this case.
