Add checksum file(s)

Hey!

I already do it for the flatpak and homebrew releases so it's not an issue to add it to the rest. I'll do it in a moment.

[JetpackDuba]

Done!

Done!

I saw the SHA256SUM file published yesterday for release 1.3.1.

I think there is a problem with current file:

ef29def5d0ffed54fe1f8b48049be939ff24b04082a683406bc4d29859a360cc linux x86_64

The right-hand part of every line should contain the actual filename of the binary (e.g.:
Gitnuro-linux-x86_64-1.3.1.jar) not those explanation words like linux x86_64 -- please note there are 2 (two) spaces between the two words:

ef29def5d0ffed54fe1f8b48049be939ff24b04082a683406bc4d29859a360cc  Gitnuro-linux-x86_64-1.3.1.jar

For comparison, here is the SHA512SUM file for Debian .iso images:
