Rob Findley 1fc30e1f4c internal/lsp/regtest: remove redundant T and ctx params from regtest funcs
In an effort to be idiomatic, I made the regtest func signature
func(context.Context, testing.T, *Env), despite the fact that Env
already has a Context and a T.

This just ended up causing more confusion, as it's not clear which
Context or T to use. Remove this and just use the fields on Env.
