Fail patch-package on incorrectly versioned patches

What does this MR do and why?

Fail patch-package on warnings

This upgrades patch-package to the latest version. The key feature wanted was the addition of the --error-on-warn flag, added in 6.5.0 via https://github.com/ds300/patch-package/pull/345.

This allows us to ensure that patch files are always kept up-to-date, which is easy to miss during Rails upgrades.

Bump @rails/ujs patch

This fixes a warning from patch-package about an old patch version.

This is a follow up to !132044 (merged), that caused this warning on running yarn install:

Warning: patch-package detected a patch file version mismatch

  Don't worry! This is probably fine. The patch was still applied
  successfully. Here's the deets:

  Patch file created for

    @rails/ujs@7.0.6

  applied to

    @rails/ujs@7.0.8

  At path

    node_modules/@rails/ujs

  This warning is just to give you a heads-up. There is a small chance of
  breakage even though the patch was applied successfully. Make sure the package
  still behaves like you expect (you wrote tests, right?) and then run

    patch-package @rails/ujs

  to update the version in the patch file name and make this warning go away.
