Allows for better per platform default config. Currently the
default serves windows/macos fine while it has to be tweaked
in order to build for linux
make build-tauri now successfully runs where it errored out before.
Appimages made with make alone however is incomplete as there are
still post processing steps in the github release workflow to bundle
additional resources.
- split platform specific config out of tauri.conf.json into auxiliary
platform specific config files, natively supported by tauri
- pull improved defaults out of template-tauri-build-linux-x64.yml
into new tauri.linux.conf.json
- fix tauri-build-linx-x64.yml to utilize new tauri.linux.conf.json
