[Development] Some tests fail even when run on fresh clone

[hexaltation]

Describe the current behavior

Submitting PR #1181 I discover that some tests fails.
Ex. Fork
Testing locally I can't maid them pass, even when removing all my changes.
Testing on main branch, the same tests fails.

I've done a experiment with PR #1184

• Create a new branch from main
• Change a word in CONTRIBUTING.md
• Push and submit PR
• Most at least 4/9 steps fail

Steps to reproduce

1. Have a fresh clone, stay on main branch
2. Setup the environment according to https://github.com/gristlabs/grist-core/blob/bbb9071175616890848993b85413de6b044b4052/documentation/develop.md
3. run

GREP_TESTS="Fork" yarn test

Describe the expected behavior

Tests must pass when run in dev environment on main branch.
