2. What did you expect to see?

Versions that match

3. What did you see instead?

There is a big gap between the version that tiup offers and the one on GitHub

4. What version of TiUP are you using (tiup --version)?

1.8.2 tiup
Go Version: go1.17.5
Git Ref: v1.8.2
GitHash: a2912cf0470d651ce724e6c4e79871ec772abe38

The problem with this is that the old version is missing newer features like slack integration and may not have all security updates.
