rule to propose using `wg.Go`

[chavacava]

Go 1.25 adds the method func (wg *WaitGroup) Go(f func())
This method allows rewriting code like

wg.Add(1)
go func() {
	defer wg.Done()
	doSomething()
}()

into

wg.Go(func() {
	doSomething()
})

revive could spot code fragments where the new method can be used to replace the more verbose (and sometimes fragile) legacy idiom.

rule name: use-wg-go (or use-waitgroup-go)

A prototype implementation of the rule can be found at the sandbox branch
(the rulename in the branch is deleteme)
You can run the rule with revive -config deleteme.toml ./...
