Update Muon to 0.5.0

(Resubmission of stale PR)
This change adds an offline compatibility table to the plugin (populated by a JSON file fetched from our documentation repository: https://github.com/wtlnetwork/muon-docs). This is to allow people to view which games are compatible with our plugin while offline. The JSON file is cached locally on plugin load. The reason this JSON is dynamically fetched is to allow new games to be added to the list as they are tested without requiring a whole new package. I checked via Discord whether it is permissible to fetch JSON in this way, and the conclusion was that it would be allowed.

The change also adds an option to select a network channel and band (i.e. 2.4 GHz or 5 GHz). This is to allow a more reliable connection, and to allow people to avoid congested bands. To ensure compliance with the WiFi regulations of various countries, we have included only universally permitted channels: 1, 6, 11, 36, 40, 44 and 48.

We have also made adjustments to the firewall handling. Instead of amending the Steam Deck's main firewall zone, the plugin now creates a dedicated 'muon-hotspot' firewall zone which is associated with only the access point interface. This means that the necessary firewall rules to make access to locally-hosted game servers possible now only apply when Muon is active.

Task Checklist

Developer

• I am the original author or an authorized maintainer of this plugin.
• I have abided by the licenses of the libraries I am utilizing, including attaching license notices where appropriate.
• Generative AI was NOT used to write a majority of the code I am submitting.

Plugin

• I have verified that my plugin works properly on the Stable and Beta update channels of SteamOS.
• I have verified my plugin is unique or provides more/alternative functionality to a plugin already on the store.

Backend

Yes: I am using a custom backend other than Python. (The plugin utilises Bash scripts in order to activate/deactivate the hotspot and perform networking tasks)

No: I am using a tool or software from a 3rd party FOSS project that does not have it's dependencies statically linked. (The plugin depends on hostapd and dnsmasq in order to perform network operations - namely, activation/deactivation of the hotspot and service DHCP requests for clients. The binary files are correctly handled via the remote binary handling options withing the packages.json file)

No: I am using a custom binary that has all of it's dependencies statically linked.

Community

• I have tested and left feedback on two other pull requests for new or updating plugins.

The package.json in this PR is referring to a file that no longer exists on Valve's servers. When I try to install the plugin, there's no error but the plugin just doesn't appear in the list.

https://steamdeck-packages.steamos.cloud/archlinux-mirror/extra-main/os/x86_64/dnsmasq-2.91-1-x86_64.pkg.tar.zst

Given that Valve only ever has the latest version of each package available on their mirror, is it a good idea to hardcode a dependency version in the plugin?

See wtlnetwork/muon#35 for the upstream bug report.
