Updates / Plugin Dependencies: Improve localized strings

[swissspidy]

[57545] introduced many new localized strings, especially in updates.js.

Many of them are using _x() incorrectly or unnecessarily. So there's definitely room for improvement here.

Then there are dependencies separated by "|" (pipe) character instead of using wp_get_list_item_separator().

Also some usage of sprintf() that could be improved.

There might be more strings that need improvement. These are just the ones I found at first glance after looking at https://core.trac.wordpress.org/changeset/57545

I think the comments plugin or theme are there for a reason. Some locales might translate the same word into different strings depending on context. Could a translator comment be added to each string instead of using _x?

[swissspidy]

That „Activate“ string doesn‘t need context though and has happily existed without context for years. If anything we‘d change this consistently throughout the code base.
A translator comment is not an adequate replacement for context, as it will just result in 1 string with multiple different comments for translators.

Note: this plugin cannot be activated until the plugins that are required by it are activated.

We generally capitalize the letter after Note:.
So, it could be

Note: This plugin cannot be activated until the plugins that are required by it are activated.

Another example:

Note: this plugin cannot be deactivated or deleted until the plugins that require it are deactivated or deleted.

Looked at this with fresh eyes today after checking the rest of the code base and also what the code looked like in previous releases.

Ended up changing my view and added context where in doubt, rather then removing it.

In short, if we use _x( 'Activate', 'plugin' ), let's make sure we use it everywhere like this.

@rabmalin Good point. Updated the PR accordingly.

In 57714:

Upgrade/Install: Improve localized strings related to plugin/theme installation and activation.

Adds context to strings where applicable to disambiguate them, coherently throughout the admin. Also improves some of the strings introduced in [57545] to ease localization.

Props swissspidy, costdev.
Fixes #60630. See #22316.
