This patch will check if browser channel is already installed.
If it is, it'll abort installation with the following error:
```
aslushnikov:~/prog/playwright$ npx playwright install msedge
Failed to install browsers
Error:
╔═════════════════════════════════════════════════════════════════╗
║ ATTENTION: "msedge" is already installed on the system! ║
║ ║
║ "msedge" installation is not hermetic; installing newer version ║
║ requires *removal* of a current installation first. ║
║ ║
║ To *uninstall* current version and re-install latest "msedge": ║
║ ║
║ - Close all running instances of "msedge", if any ║
║ - Use "--force" to install browser: ║
║ ║
║ npx playwright install --force msedge ║
║ ║
║ <3 Playwright Team ║
╚═════════════════════════════════════════════════════════════════╝
```
To re-install browser channel, use `--force`.
