Type of change

- [ ] New feature development
- [x] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other

Objective

With #5038 being now merged, you should build the snap with the compression algorithm that gives the best results for desktop apps; according to Canonical, the use of the LZO compression offers 40-74% cold startup improvements over the XZ compression:

• https://snapcraft.io/blog/snap-speed-improvements-with-new-compression-algorithm

Code changes

I've just added the compression option in the top snap key, and configured the value to lzo

Should fix #2609

Bump; come on let's get this merged. The snap is very slow still.

@pachulo Thank you for your contribution and apologies on the long wait for a review.

With #7448 we also bumped the snap-core version from core18 to core22, which we expect to bring some more improvements for the Bitwarden snap.

Approving the changes. Going to create a separate branch to kick-off all the build workflows, which will gives us feedback on new file-sizes. Then passing it on to QA for testing.

Didn't quite get why AppImage is complaining, because we are changing the compression for snap. We'll need to look into it. Seems this issue has been reported at electron-userland/electron-builder#7013
