update mysql-using-spire example to use latest versions of these Helm Charts

[developer-guy]

Right now, the Helm Charts used in the mysql-using-spire example are pretty old, that'd be great if you could update the latest versions of Helm Charts and make necessary changes on the values files according to that update.

Are there any changes you know of other then the version number bump needed?

The first issue was when I remove the versions from the SPIFFE chart for both crds and spire I don't see any x500UniqueIdentifier value in the output of the openssl command and the second issue was mysql-values.yaml didn't work with the latest version of the mysql Helm chart it was failing with this Error: invalid_reference: invalid tag
