Tool: update AMReX dependency (#1710)

* Tool: update AMReX dependency

We currently pull the `development` branch of AMReX in CMake builds.

This is problematic in central workflows:
- checking out a release might not compile
- manual intervention is needed by users
- builds are not as reproducibile as they could be
- CI fails in a surprising wary in WarpX if a temporary bug is lands
  in AMReX' `development`

Instead, we can bump the AMReX requirement periodically in a PR.
This migh be the case when we:
- need new features or bug fixes
- do a release

Manual updates guarantee that we see problems with updates from
AMReX in the moment they are introduced - during a PR that changes
the dependency to AMReX.

* Tool: update PICSAR dependency

See AMReX' updater description.

* Docs: Dependencies & Releases

-Create a new Github release
----------------------------
-
-WarpX has one release per month.
-In order to create a release, you need to:
-
- 1. Create a new branch from ``development`` and update the version number in all source files.
-    There is a script for that, so you can do:
-
-    .. code-block:: sh
-
-       cd Tools/DevUtils/
-       ./update_release.sh # This replaces the old version number with the new one.
-
-    Then open a PR, as usual. NOTE: do not merge this PR before step 2 is completed.
-
- 2. Click the ``Draft a new release`` button at https://github.com/ECP-WarpX/WarpX/releases and follow instructions.
-    Please specify the compatible versions of dependencies (see previous releases), and provide info on the content of the release.
-    In order to get a list of PRs merged since last release, you may run
-
-    .. code-block:: sh
-
-       git log --since=<date> | grep -A 3 "Author: " | grep -B 1 "\-\-" | sed '/--/d' | sed -e 's/^    /- /'
-
-    where ``<date>`` is the date of the last release, say ``2020-05-01`` if the last release was on May 1, 2020.
-
- 3. Optional: create a ``release-<version>`` branch, write a changelog, and backport bug-fixes for a few days.
