Restore link checking on pushes

[pomerantsev]

I disabled link checking when I was working on analytics:

accented/.github/workflows/website.yml

Lines 32 to 40 in 1e91418

	# - name: Install lychee
	# if: github.ref != 'refs/heads/stage'
	# uses: ./.github/actions/installLychee
	# - name: Check links
	# if: github.ref != 'refs/heads/stage'
	# run: ./packages/website/scripts/checkLinks.mjs --local
	# env:
	# GITHUB_TOKEN: ${{ secrets.LINK_CHECK_TOKEN }}

Figure out what's wrong with it and how to fix it.
