Typo: `overriden` -> `overridden`

[aristath]

Just a simple, common typo we have in a couple of places in our codebase.
This has been merged in Gutenberg (see ​https://github.com/WordPress/gutenberg/pull/48711), and this ticket is to backport these changes to Core.

Trac ticket: https://core.trac.wordpress.org/ticket/58464

Please note that there are a couple of other instances where overridden is typed incorrectly, but those instances are in files that are directly included from 3rd-party libraries, so these were not modified in this PR.

There are few files where this typo exists. I changed all those

Please note that these additional instances are in files that are part of 3rd-party libraries - as noted in the PR. That is why they were not modified and were kept intact. 3rd-party libraries should be updated separately, in their own repositories and not as part of WP because that just makes maintenance easier when there is an updated version of those libraries.

This is the final one

Understood.
Then I think you patch is perfect.
