[Feature]: Add `# Playwright` comment to `.gitignore` entries added by `playwright`

[hamirmahal]

🚀 Feature Request

Current behavior

npm init playwright@latest results in

$  cat .gitignore 
# Previous .gitignore entries...
node_modules/
/test-results/
/playwright-report/
/blob-report/
/playwright/.cache/

Desired behavior

I think it'd be nice if npm init playwright@latest resulted in

$  cat .gitignore 
# Previous .gitignore entries...

# Playwright
node_modules/
/test-results/
/playwright-report/
/blob-report/
/playwright/.cache/

instead.

Example

No response

Motivation

It helps readability when .gitignore entries are separated into appropriate sections.

For example, see .gitignore after doing npx create-next-app@latest

$  cat my-app/.gitignore 
# See https://help.github.com/articles/ignoring-files/ for more about ignoring files.
