Docs: Typo correction – 'compatability' to 'compatibility'

[truptikanzariya]

There is a small typo in the following file:

src/wp-includes/html-api/class-wp-html-tag-processor.php

The word "compatability" is misspelled and should be corrected to "compatibility".

Incorrect:
No-quirks mode document compatability mode.
Quirks mode document compatability mode.

Corrected:
No-quirks mode document compatibility mode.
Quirks mode document compatibility mode.

This fix improves accuracy and maintains consistency with the correct spelling used elsewhere.

@dhruvang21 I think there are a lot more instances where the word compatability is used throughout the codebase.
For instance -

​https://github.com/WordPress/wordpress-develop/blob/4dd067fb80096acf764e9732f7cfddc4d433b485/src/wp-includes/html-api/class-wp-html-doctype-info.php#L129-L136

I noticed the typo is also present in variable names like $this->indicated_compatability_mode. I’d like to fix those too, but since it affects functionality, I’ll ensure all references are updated. Please let me know if there are any backward compatibility concerns I should be aware of.

@himanshupathak95 I also noticed that there are additional instances where typos need to be fixed. However, I agree with @getsyash — I think it’s best to wait for input from the reviewers, as they’ll definitely help guide us and suggest the appropriate solutions.
