Changes:
- Added a /software page, a page where users can manage
(upload/edit/download/delete) software installers on their Fleet
instance across multiple teams at once.
- ~~Removed the `deploy-bulk-operations-dashboard-on-heroku` GitHub
action (This dashboard will be hosted in Render in the future)~~
Reverted this change to unblock merging this PR, I will remove this file
in a separate PR.
