CI cannot run on PRs from forks because repo variables are not shared with forks

[surchs]

For example #63. This is annoying because it's now extra work to figure out of the tests are failing for a good reason or just because of the fact that the variables are not shared. Even worse, dependabot counts as a fork too, and based on this discussion: https://github.com/orgs/community/discussions/44322 we can expect that dependabot runs will have the same issue.

Right now, we only use repo variables in two workflows:

query-tool/.github/workflows/component-test.yaml

Lines 17 to 19 in 99fc5c0

	- name: Create .env file
	run: |
	echo -e "NB_API_QUERY_URL=${{ vars.NB_API_QUERY_URL }}\nNB_IS_FEDERATION_API=${{ vars.NB_IS_FEDERATION_API }}" > .env

and

query-tool/.github/workflows/e2e-test.yaml

Lines 22 to 24 in 99fc5c0

	- name: Create .env file
	run: |
	echo -e "NB_API_QUERY_URL=${{ vars.NB_API_QUERY_URL }}\nNB_IS_FEDERATION_API=${{ vars.NB_IS_FEDERATION_API }}" > .env

and there is only one variable that could realistically change (the API URL). I suggest we

• get rid of the repo variables
• update the e2e workflow to hardcode the API URL
• update the component test workflow to also hardcode the API URL
