Upgrade to keytar@7.6.0 and build arm binaries.

[SethFalco]

Adds support for building binaries that will run on arm64/aarch64 devices.

Warning

I have only tested the arm builds on my PinePhone (Linux) and can vouch it works well.
I have no way, or at least don't know of a way, to test the Windows or macOS builds.

Changes

arm64 Binaries

Adds the arm64 arch to all build targets.
This also requires renaming artifacts to tutanota-os-arch.ext, this avoids arch builds from overwriting the previous.

Upgrading keytar

keytar 7.4.0 adds Linux arm64 prebuilt binaries. atom/node-keytar#352

This upgrades keytar to 7.6.0, this is not the latest version.
keytar 7.7.0 (latest) moves to using NAPI prebuilds (atom/node-keytar#331), however electron-builder is being a pain with fetching those binaries.

There is a workaround for this, but I figured for now it'd be simpler to stick with the latest non NAPI release, and shift over later once electron-builder handles that case better.
atom/node-keytar#380

.gitignore dist

Was there a reason this wasn't there before?

Hey
Thanks a lot for the PR!

We are actually switching to building keytar on our own, do you think we can cross-compile easily? There's PR for that #3016

do you think we can cross-compile easily

I've never dealt with native dependencies or cross-compiling architectures before, unfortunately. ^-^'

It's certainly possible, that's what keytar themselves are doing. atom/node-keytar#352
I don't know if it's "easy" in this case, though.

I can explore the referenced PR later; we'll see with that branch if I can get the build working on my PinePhone.

@SethFalco thanks! We will first finish up building keytar and can look into ARM after that

Now that #3016 is closed is ARM support something that's being considered?

[charlag]

It would take some work to cross-compile things so we would appreciate help with that

Hi
We will be dropping Keytar anyway and we will revisit ARM builds later
