docs: added full E2E documentation to the project README (!1489) · Merge requests · Perun / Perun IdM / perun-web-apps · GitLab

Bc. Jakub Hejda requested to merge hejda/ST-1296/E2E_documentation into main Dec 14, 2023

We had a full documantation for E2E test on Confluence before.
After the migration to the GitLab this documentation needed some changes, so it was fixed, appended by new sections, translated to EN and moved to the repozitary.

Closes ST-1296
