Replace `temp` package with vendored code to avoid deprecated `rimraf` transitive dependency

[kitten]

This is simply to avoid the dependency chain on rimraf via temp@0.8.4 -> rimraf@2.6.3, which has been deprecated. The temp package hasn't seen a release in a while, and minimal functionality is used from it. The temp.track functionality also doesn't seem to be used, which would make it pretty trivial to vendor the code.

Switching to alternatives like tempy likely isn't attractive either since it's ESM-only while jscodeshift is not. Older versions of tempy also depend transitively on deprecated versions of rimraf.

Tests pass and cover changes as-is.

Note: The vendored code has an added copyright notice line for node-temp.

@Daniel15: Sorry about that! ❤️ There's a test in the latest commit now that checks that the remote transformer files actually work.
