[Feature] Add Remark plugin npm2yarn

[cpAdm]

In many places in the docs we have the following source code:

<Tabs
  groupId="js-package-manager"
  defaultValue="npm"
  values={[
    {label: 'npm', value: 'npm'},
    {label: 'yarn', value: 'yarn'},
    {label: 'pnpm', value: 'pnpm'}
  ]
}>
<TabItem value="npm">

\```bash
npx playwright codegen playwright.dev
\```

</TabItem>

<TabItem value="yarn">

\```bash
yarn playwright codegen playwright.dev
\```

</TabItem>

<TabItem value="pnpm">

\```bash
pnpm exec playwright codegen playwright.dev
\```

</TabItem>

</Tabs>

This can be reduced to:

\```bash npm2yarn
npx playwright codegen playwright.dev
\```

Some places only mention npm commands, with this approach these commands can easily be rewritten. Also, if bun gets supported its very easy to add the new tab once, in the config.
