Add electron build pipelines for nightly and release

[GuessWhoSamFoo]

Which issue(s) this PR fixes

• Fixes add build-electron-prod to build.go #1479, add electron asset building to our github actions #1480

Special notes for your reviewer:
Additional changes (in future PRs) which should follow:

• Switch from using goreleaser containers in asset building to goreleaser/goreleaser-action@v2. The action now allows an install-only mode to handle any pre-processing in the same runner. This can skip the upload/download steps for bundled assets files.
• Wait for glob support on actions/upload-release-asset@v1. Although goreleaser supports uploading arbitrary files (feat: upload extra files to the release goreleaser/goreleaser#1333), it needs post processing of checksums.txt before upload which is not supported.
• Ensure octant node subprocess can access local filesystem/env vars. The octant subprocess in electron does not have access to the local filesystem or environment variables and asks for a kubeconfig each time.
• Synchronize version across front and backend code. electron-builder enforces semver in package.json so version bumps need to happen in two places. Documentation and/or automation is needed to avoid potential mismatch.
• Investigate high CPU usage. Something about running octant in this mode is causing CPU spikes at launch.
• Electron nightlies are relatively large files so the current behavior is to overwrite old uploads.
• Add a build flag to exclude front end bundles from go build ....

This is looking great, one minor fix that will also remove a TODO item and this is ready to merge.
