pmaport for ubports-installer

The installation instructions for fairphone-fp5, fairphone-fp4, and shift-axolotl all suggest using ubports-installer to flash the device, but ubports-installer is not packaged on postmarketOS (nor Alpine).

ubports-installer was the first option in the installation instructions, and I mis-interpreted this as implying that it is the recommended option. This was a mistake.

I tried hacking an APKBUILD. This is the results after several iterations:

maintainer="not me"
pkgname=ubports-installer
pkgver=0.10.0
pkgrel=0
pkgdesc="Simple tool to flash mobile devices"
url="https://github.com/ubports/ubports-installer"
license="GPL3.0-or-later"
arch="all"
depends="nodejs"
makedepends="npm electron-dev"
source="ubports-installer-$pkgver.tar.gz::https://github.com/ubports/ubports-installer/archive/refs/tags/$pkgver.tar.gz"

build() {
	npm i
	npm run build
	./node_modules/.bin/electron-builder --linux --x64 --dir -c.electronDist=/usr/lib/electron -c.electronVersion="$(cat /usr/lib/electron/version)"

	# Remove a bunch of binaries for other platforms.
	find ./dist/linux-unpacked/resources/app.asar.unpacked -type d \( -name linux -o -name mac -o -name win32 -o -name darwin \) -print -exec rm -rf {} + ;
}

check() {
	npm run test
}

package() {
	cd dist/linux-unpacked/
	find . -type f -exec install -Dm644 {} -t "$pkgdir/usr/share/$pkgname/" \;
}

"

This builds, but the resulting package does not work:

I'm not moving further with this, but, as discussed on IRC, I'm leaving this here so that the work does not get lost and to have a single place to track this missing package.
