Review comment:
Scratch that, we can tag certain files or folders with `export-ignore`
in the .gitattributes file. This is the proper way to exclude them from a git
archive command as it's built into git itself. This would also allows us to
skip the admittedly large amount of shell commands that are going into this.
And while some might not be familiar with `.gitattributes`, I would suspect
that a release engineer should hopefully be.
Here's the documentation on the git archive command:
https://www.linux.org/docs/man1/git-archive.html
And here's a post discussing the usage of `export-ignore` in the
`.gitattributes` file to properly ignore files.

I think this is the best approach as it uses the in built tools of git for
generating this (so hopefully it should be better understood by release
engineers), and it involves way less shell munging than currently.
An example .gitattributes file for the excludes we want would be something
like
```
/build export-ignore
/examples export-ignore
.jitpack.yml export-ignore
/python export-ignore
/site export-ignore
```
The above complicated set of `excludes`, `archives, etc could instead be
used off of the tag that is already pushed earlier in the script.
```bash
# Assuming the .gitattributes file is set up with the appropriate
export-ignore
git archive --prefix $tag/ -o $tarball --worktree-attributes $tag^{tree}
```
I am going to open a PR for adding a `.gitattributes` file so we can test
with that. You can feel free to add it to this branch if you prefer, but I
can't push to this branch so it's easier for me to create a separate PR.
