Disallow Google GSON 2.10 or higher due to removed methods

[sbluhm]

What does this PR change?

1. Disallow Google GSON 2.10 or higher due to removed methods.
   Salt communication fails otherwise with a class not found exception when accessing the Salt keys page.
   (GSON 2.10 is available in the Enteprise Linux 9 repos)

2. Remove minimum GSON requirement. What would install a lower version?

let's wait for the tests, but I think in this way we should be safe.
