feat: flatpak support

[wiiznokes]

update the manifest for flatpak suport.

• removed the just module because it was installed in the final package
• put the app icon in scalable dir, and remove other because its redundant
• rename some file
• put the same appid everywhere
• fr translation
• add cargo-source.json
• simplification of the justfile

Note:

for generating the cargo source:

git clone https://github.com/flatpak/flatpak-builder-tools
python3 flatpak-builder-tools/cargo/flatpak-cargo-generator.py ./Cargo.lock -o cargo-sources.json

for building and installing

flatpak-builder \
        --force-clean \
        --verbose \
        --ccache \
        --user --install \
        --install-deps-from=flathub \
        --repo=repo \
        flatpak-out \
        dev.edfloreshz.CosmicTweaks.json

I tested and everything seems to work (expect the spacing and padding stuff but i think it unrelated because other change of the config works)

[wiiznokes]

note that it may be preferable to create the flatpak repo now @edfloreshz, and i can create a pull request there to avoid merging the big cargo-sources.json. But you can already test the flatpak with this branch.

[edfloreshz]

On second thought, could you change dev.edfloreshz.Tweaks to dev.edfloreshz.CosmicTweaks? Given that this is a COSMIC specific app, i think it would be a better fit.

Sorry about that 😅

[edfloreshz]

I'm currently traveling 🧳 , it may be a while before I can create the repository, we can hold this PR until then.

[wiiznokes]

Yeah np

[edfloreshz]

Perfect! I'll review when I'm on my laptop 💻 thanks

[edfloreshz]

I'm reviewing the PR, could you rebase it with the latest changes?

[edfloreshz]

Should this file be pushed?

[wiiznokes]

Probably not, see #23 (comment)

[edfloreshz]

You can go ahead and delete it, I already pushed it to https://github.com/edfloreshz/flathub/tree/dev.edfloreshz.CosmicTweaks

[edfloreshz]

Some minor changes

[wiiznokes]

I'm reviewing the PR, could you rebase it with the latest changes?

Done

[edfloreshz]

I'll try to make the Flathub repo tomorrow.

[edfloreshz]

Can you remove this file? I'm creating the repo but I need to merge this first.

[edfloreshz]

I'll merge and delete the file later, I'm a bit short on time and I want the Flathub submission to proceed while I'm gone.
