`.nx/` makes all-contributors plugin think info has changed, crashes pipeline

**Describe the bug**

I am unable to find any mentions of `nx` in this repo (the private repo this is failing on doesn't use `nx`), but for some reason, a `.nx/` folder is being added when I use `yarn auto shipit -vv` on our `master` branch, which runs the all-contributors plugin. As far as I can tell, it's not coming from our end, because we don't use `nx` AND we run `git reset --hard` right before calling `auto`.

Re: [this discussion](https://github.com/nrwl/nx/discussions/20605#discussion-5930428), when working with `nx` >= 17, the `.nx/` folder has been moved from `node_modules/.cache` to the workspace root. This is causing `changedFiles` in the code below to be true, which makes the plugin think that the README and .all-contributorsrc have been updated. The plugin tries to commit these files and errors out because those files actually have not changed.

https://github.com/intuit/auto/blob/335fadb33fc1b661faa2a82a1d992b0e81036a74/plugins/all-contributors/src/index.ts#L360-L366

Here is the error shown with `-vv`

```
The following paths are ignored by one of your .gitignore files:
fastlane/README.md

On branch master
Untracked files:

.nx/

nothing added to commit but untracked files present (use "git add" to track)
Error: Running command 'git' with args [commit, --no-verify, -m, "Update contributors [skip ci]"] failed

On branch master

Untracked files:

```

**To Reproduce**

I will try to reproduce this with a small repo. TBD.

**Expected behavior**

I expect `auto` to:
1. not crash my pipeline
2. gracefully handle it when a user has not meet any new contribution criteria and `shipit` is called on `master`

**Environment information:**

```txt
Environment Information:

"auto" version: v11.0.1
"git" version: v2.39.3 (Apple Git-145)
"node" version: v16.20.2
GHE version: v3.10.8
```

**Additional Context**

* I was able to workaround this on our pipeline by adding `.nx/` to our `.gitignore`.
* We don't use `.nx/` in the repo this issue was discovered on, so not sure where it's coming from
* This issue is happening for `master` but not for other branches. I didn't test `next`
