Was able to run on Ubuntu 22.04

Summary

I was able to run the app on Ubuntu 22.04 but had to change the following

Pile/src/main/utils/store.ts

Lines 4 to 6 in 234aa90

	if (!safeStorage.isEncryptionAvailable()) {
	throw new Error('Encryption is not available on this system.');
	}

to

const useEncryption = safeStorage.isEncryptionAvailable();

Also the contributing guide doesnt has any info on how to build and run the program.
