Rename script is overwriting the `stactools-packages` group name

[cuttlefish]

The rename script is mangling docker/env. sed implementation of regex doesn't support lookahead. This makes it difficult for it to recognize the difference between stactools-package and stactools-packages. The former should be rewritten, the latter should not. [I may be missing a simple option here]

As I see it we can:

• Switch to more robust regex tool. The downside is that we now introduce a dependency that might not be properly installed.
• Change the token to be rewritten from package to something else that won't conflict. template? We might hit similar problems down the road. It's nice having a name that is still valid syntactically because we can test the template repo on its own.
• Switch to a proper templating system. That seems likely to be too much work. Although it might help with a more robust solution for #23. At that point I'm not sure if a GitHub template repo is even the correct way to handle it... 🤷

Could we do a really hackey "move out of the way" sort of thing, e.g.

1. Change stactools-packages to stringthatwellchangebacklater
2. Update all stactools-package
3. Change stringthatwellchangbacklater to stactools-packages

That's definitely an option 😆 I forgot to included it. I guess I'd rather change the package magic word, since it conflicts with other things as well. Neither solution is stellar, but I don't think anything more complex is warranted at the moment.

Worksforme!

👍 I'll take a look at it this afternoon
