Show time since when a feed has problems + new timeago() method and i18n plurals (#8670)

Closes https://github.com/FreshRSS/FreshRSS/issues/8508

Changes proposed in this pull request:

- Use an integer for `Feed::error` everywhere (follow up to #8646)
- Extract `Entry::machineReadableDate()` into function for use in HTML templates
- Add `timeago()` function that converts a unix timestamp into a "4 weeks ago" string
- Show the last successful feed update, and the last erroneous update

How to test the feature manually:

1. Update a feed
2. Modify the feed URL in the database and set it to a non-existing URL
3. Update the feed again
4. Open the "Manage feed" and see the expanded error message:

>  Blast! This feed has encountered a problem. If this situation persists, please verify that it is still reachable.
> Last successful update 3 hours ago, last erroneous update 1 hour ago. 

You can hover the relative dates to see the timestamp.

* Make Feed::error an int everywhere

Related: https://github.com/FreshRSS/FreshRSS/pull/8646

* Extract timestamptomachinedate()

.. for later usage in the feed error time display.

* Show time since when a feed has problems

We add our own "timeago" function that converts a unix timestamp
into a "4 weeks ago" string.

Resolves: https://github.com/FreshRSS/FreshRSS/issues/8508

* Add new translation keys

* i18n fr, en-US

* Minor XHTML preference

* Slightly shorter rewrite, also hopefully easier to read

* Rewrite to allow (simple) plural
I also moved some functions around for hopefully a more generic and better structure.
I made some changes for the sake of speed (e.g. second-based logic instead of datetime intervals).
Note: I used automatic translation as I was worried it would be too complicated to explain to translators... I proofread the few languages I have some familiarity with.

* Add reference to CLDR

* Slightly more compact syntax

* Always show last update, fix case of unknown error date

* Remove forgotten span

* No need for multi-lines anymore

* Fix error date thresshold

* plurals forms

* Extract gettext formula conversion script to cli

* Simplify a bit

* Escort excess parentheses to the door

* Simplify

* Avoid being too clever in localization

* Fix German

* Fix plural TODO parsing

* Ignore en-US translation

* make fix-all

* git update-index --chmod=+x cli/compile.plurals.php

* Heredoc indent PHP 7.3+

* compileAll: Continue on error

* PHP strict comparisons

* Light logical simplification

* Cache plural_message_families

* Avoid case of empty value

* A bit of documentation
