test(frontend): homepage snapshots (logged in and logged out states)

[DenysKarmazynDFINITY]

Motivation

The goal of this PR is to add basic snapshot tests for homepage (user logged in and logged out states).

Changes

1. Basic Playwright code.
2. To properly compare homepage screenshots, I deactivate the infinite Hero background animation before taking a snapshot.
3. Added data-tid to the related elements on the page.
4. Added generated screenshots to git to have a baseline for future comparisons.

Tests

Please see the committed screenshots.

Dockerfile.e2e fails with a similar error I faced yesterday while setting up the project locally. On it.
