zed --version not working

Description:

Users are reporting their Arch builds of Zed are missing version numbers https://github.com/zed-industries/zed/issues/14859

Specifically they are complaining that the --version flag does not work as expected. This is a relatively easy fix, you just need to export RELEASE_VERSION at build-time.

You can see an example in the Zed build-linux script: https://github.com/zed-industries/zed/blob/main/script/bundle-linux

Additionally, it looks like your build script is not running script/generate-licenses and so the binaries you are building likely do not include the necessary license assets for display in-application. (ctrl-shift-p zed: open licenses).

Apologies for not packaging this as a PR, I don't currently have an Arch Linux setup to test on.

Thanks!
