make sure workflows run for create-pull-request ("update dependent-usage.json" PRs)

[brian-smith-tcril]

I did some investigation when trying to figure out why on: pull_request workflows didn't run for #3379

I left a few comments on that PR that I'm copying here:

Looking into why tests aren't running when these PRs are made:

The PRs are made using

paragon/.github/workflows/analyze-dependents.yml

Lines 262 to 271 in 81a0abf

	- name: Create pull request for dependent project usages
	id: cpr
	uses: peter-evans/create-pull-request@v7
	with:
	commit-message: "docs: update dependent-usage.json"
	title: "docs: update dependent-usage.json"
	body: "Contains automated changes to the dependent-usage.json file, which provides the data for Paragon Usage Insights."
	labels: automerge
	branch: dependent-usage-analyzer/update-dependent-usage-json
	base: next

The README for the create-pull-request action we're using says (https://github.com/peter-evans/create-pull-request?tab=readme-ov-file#token)

If you want pull requests created by this action to trigger an on: push or on: pull_request workflow then you cannot use the default GITHUB_TOKEN. See the documentation here for further details.
