#15556
We will need to pay attention when releasing fleet (the github actions
were modified to use the local file now).
Should be reviewed by commits (first commit is the actual adding of the
`version.go` file)
- [X] Manual QA for all new/changed functionality
Manually tested the following:
- `Settings -> My account` on the UI and checked the `/version` endpoint
response. (Or also visiting https://localhost:8080/version on a
browser).
- Ran `make fleetctl fleet`, `./build/fleetctl --version` and
`./build/fleet version`.
