Unnecessary newline in arguments when putting type parameters on a separate line

[ainar-g]

gofumpt --version

v0.4.1-0.20230125043819-8b5f734ef391 (go1.20.1)

Before:

package main

func f[
    T any,
](v T) (ok bool) {
    _ = v

    return true
}

func main() {
    _ = f(42)
}

After:

package main

func f[
    T any,
](v T,
) (ok bool) {
    _ = v

    return true
}

func main() {
    _ = f(42)
}

Notice how there is now a comma and a newline after v T. Go 1.20.1's gofmt does not add it. In my opinion, gofumpt should not add this newline.
