Disable corrections for homepage search field

As part of our work on site search, we've discovered a pain point where
mobile browsers' autocorrection features mess up user queries,
especially when it comes to domain specific terminology. For example,
searches for "HMRC" are frequently autocorrected to "Hercules", or
searches for "SORN" to "sworn".

- Bump `govuk_publishing_components` to 40.1.0
- Set `disable_corrections` parameter to `search` component in homepage
  header
