tec: Update the lib_opml (#4403)

* fix: Fix undefined GLOB_BRACE on Alpine

The manual states that:

> Note: The GLOB_BRACE flag is not available on some non GNU systems,
> like Solaris or Alpine Linux.

This generated an error on Alpine.

Reference: https://www.php.net/manual/function.glob.php

* fix: List details of feeds for OPML exportation

The details are necessary to export the XPath information, the CSS full
content path and read actions filters.

* Update LibOpml to 0.4.0

* Refactor OPML importation to be more robust

First, it fixes two regressions introduced by the update of lib_opml:

- title attribute is used when text attribute is missing;
- the OPML category attribute is used as a fallback for feeds categories.

In a related way, if also fixes a problem when a feed had both a parent
category outline and a category attribute. Before, it only considered the
attribute as its category, but now it considers the parent outline.

Then, it counts category limit correctly by not increasing
`$nb_categories` if the category already exists.

* Exclude lib_opml from the CodeSniffer

* Fix variable names when logging some errors

* Fix catch of LibOpml Exception

* Make sure to declare the category

* Exclude lib_opml from PHPStan analyze

* Disable markdownlint for lib_opml

* Fix typos

* Use auto-loading and allow updates via Composer

* Fix broken links to lib_opml

* Bring back the ability to import the OPML frss:opmlUrl attribute

* Refactor the logs of OPML errors

* Update lib_opml to the version 0.5.0
