rename repository to go-internal

It's really more than modinternal (e.g. testscript isn't related
to modules).

-This repository factors out some internal packages from the cmd/go internal package
-in the Go standard library.
+This repository factors out an opinionated selection of internal packages and functionality from the Go standard
+library. Currently this consists mostly of packages and testing code from within the Go tool implementation.
 
-It also factors out into a separate package the script-based testing functionality
-(http://godoc.org/github.com/rogpeppe/modinternal/testscript) and the Go proxy test server (http://godoc.org/github.com/rogpeppe/modinternal/goproxytest).
+Included are the following:
+
+- dirhash: calculate hashes over directory trees the same way that the Go tool does.
+- goproxytest: a GOPROXY implementation designed for test use.
+- gotooltest: Use the Go tool inside test scripts (see testscript below)
+- imports: list of known architectures and OSs, and support for reading import import statements.
+- modfile: read and write `go.mod` files while preserving formatting and comments.
+- module: module paths and versions.
+- par: do work in parallel.
+- semver: semantic version parsing.
+- testenv: information on the current testing environment.
+- testscript: script-based testing based on txtar files
+- txtar: simple text-based file archives for testing.
