Posts screen: Improve the "filter by status" links description in the Help tab

[afercia]

Noticed a couple of small things in the Help tabs that could be improved a bit:

• "upper left" is not so useful for screen reader users: references to "visual" positions should be avoided in favor of positions in the document structure; "above the posts list" is better because suggests that it's "before"
• just four possible post statuses are listed (All, Published, Draft, or Trashed) while there are many others, see screenshot below; maybe a more generic text would be more appropriate and future-proof

fixed text on help tab in edit.php

I found "upper left" on both plugin-install.php and users.php. so i fixed them. But in users.php, i didnt change texts to generic 'cause increasing user roles are less possible.

Refreshed patch merges the previous ones and replaces also references to "upper right". By the way, found many occurrences of "on the left" and "on the right" that should be changed as well.

@zakb8 thanks, "to only show posts with that status" sounds better. I'd keep "links above the posts list" though. Refreshed patch.

Refreshed patch to use a proper single quotation mark.

In 37680:

Accessibility: Help text improvements.

Avoid references to "visual" positions in favour of positions in the document
structure. The help text shouldn't assume users can see.

Also, in the Posts screen don't mention specific types of posts and use a more
generic text instead.

Props odysseygate, pansotdev, zakb8.
Fixes #34761.
