feat: Remove OCR Support

[michael-genson]

What type of PR is this?

(REQUIRED)

• cleanup

What this PR does / why we need it:

(REQUIRED)

This removes OCR from Mealie. This is done for a few reasons:

• The current OCR implementation is half-baked; there are several issues with it that usually make it easier to just type your recipes manually
• Discussion in Discord heavily leans towards no one using it, or it not working (which is the closest thing we have to actual usage data)
• Removing it helps focus contributor attention (it's currently one of the more complex features with the most bugs)
• Removing it drastically lowers build times, container sizes, and resource usage

Which issue(s) this PR fixes:

(REQUIRED)

Closes #2394
Closes #2424
Closes #2437
Closes #2451

I removed the is_ocr_recipe field from the schema, but left it in the db (since we can't easily remove it from sqlite). I also left all of the translations and the mdi-icons, in case we're able to re-purpose them. Happy to remove those if needed.

Maybe run make docs to remove the ocr endpoints from the api references

Looks Good.
Will not merge yet, as maybe somebody with more experience should have another go

I know we have our differences and as the person that wrote this feature and lost interest in maintaining it due to multiple factors, I agree fully with this decision from your point of view and I respect it. I'll continue to use mealie as long as it is the better open source recipe manager which I think that it still is.
Sometimes goals are not achieved and it's more courageous to give up.
