README: add Go 1.21.0 to the version list of our tooling

It's not a replacement of 1.20.7, because that still remains the default and 1.21.0 is downloaded only as an alternative SDK for projects that require it. Signed-off-by: Erik Skultety <[email protected]>

+* Starting with Go 1.21 Go changed the meaning of the `go` directive in `go.mod` file slightly and
+ made the constraint stricter in that the line now denotes the **minimum required** version of Go
+ instead of a suggested version of Go. If a project recommending an older version of Go is
+ processed with Go >=1.21 it might happen (based on other dependencies) that its own required
+ version of Go will be bumped to 1.21+, hence dirtying the git repo - to prevent this cachito
+ uses two releases of Go SDK concurrently.
