Load default 403/404 meta tags when node is used for those pages

Tried to apply the patch 2904468-13.patch , getting this error :

Checking patch src/MetatagManager.php...
Hunk #2 succeeded at 495 (offset 2 lines).
Checking patch tests/src/Functional/MetatagHelperTrait.php...

error: patch failed: tests/src/Functional/MetatagHelperTrait.php:4
error: tests/src/Functional/MetatagHelperTrait.php: patch does not apply

Re-rolled the patch in #14 to apply cleanly to 1.x-dev

Applied the Patch (#18) metatag-2904468-load_default_404_tags-18.patch , working as expected now the metatag values are rendering from backend 404/403 metatag settings , rather than node which is specified in 404 and 403 page settings.
Adding the screenshot for the same. We can move this to RTBC+1.

Setting to "Needs Work" because
* the latest patch seems to have lost the tests from #7
* the latest patch doesn't apply on the 1.x branch, but should probably just go on the 2.x branch anyway.

Upping to "normal" because the module is not doing what it says that it's going to do.

Rerolled for v2 and includes original tests.

My apologies. I was misusing phpcs locally and didn't catch those coding standard errors. Take 2!

Utilized the patch supplied in #24 🐛 Load default 403/404 meta tags when node is used for those pages Needs review , generated an MR containing phpcs corrections, and performed a minor code refactor.

Thanks!
