Announce: Flatpak 1.11.3 (development release)

[Simon McVittie]

This is a release-candidate for Flatpak 1.12.0.

Available here:
   https://github.com/flatpak/flatpak/releases/tag/1.11.3

Dependencies:

* For Linux distributions that compile Flatpak to use a separate
    bubblewrap (bwrap) executable, updating to version 0.5.0 is recommended,
    but not required. The minimal version is still 0.4.0.

Bug fixes:

* Don't inherit an unusual $XDG_RUNTIME_DIR setting into the sandbox, fixing
  a regression introduced when CVE-2021-21261 was fixed in 1.8.5 and 1.10.0
* Update the included copy of bubblewrap (flatpak-bwrap) to 0.5.0
    - Better diagnostics when a --bind or other bind-mount fails
    - Create non-directories with safer permissions
    - Allow mounting an non-directory over an existing non-directory
    - Silence kernel messages for our bind-mounts
    - Improve ability to bind-mount directories on case-insensitive filesystems
* Don't ask user which remote to download from if there is only one option
* Improve robustness of autogen.sh

Internal changes:

* Improve test coverage
* Spelling fixes

Translation updates: Brazilian Portuguese, Russian, Spanish, Ukrainain
