Fix tfplugindocs flow - Githubissues

Description of the change

So in this PR:

I updated everything to Go 1.19
looked up how this tool actually supposed to be used to avoid this issue in the future
I have found Hashicorp's example repo where they have it in a separate folder and separate module with it's own go.mod file and locked dependencies
so I did the same thing here
while there, I also bumped a few GH Actions
the bump to go 1.19 broke golangcilint, so i bumped golangcilint
which in turn broke one of its linters called depguard of course 😂 I fixed that in configuration
