Split up slow Playwright tests (#12741)

* Split up slow Playwright tests

To optimise parallelism

Deals with:

```
Slow test file: read-receipts/redactions.spec.ts (5.4m)
Slow test file: read-receipts/new-messages.spec.ts (3.9m)
Slow test file: read-receipts/high-level.spec.ts (3.6m)
Slow test file: read-receipts/editing-messages.spec.ts (3.1m)
Slow test file: read-receipts/reactions.spec.ts (2.2m)
Slow test file: crypto/crypto.spec.ts (2.4m)
Slow test file: settings/appearance-user-settings-tab/appearance-user-settings-tab.spec.ts (1.2m)
Slow test file: composer/composer.spec.ts (1.1m)
Slow test file: crypto/verification.spec.ts (1.1m)
```
