[process-compose] Bump version (#2040)

## Summary

Bumps to v1.5.0

Note: Because process-compose flake is not in any cache installing a new
version can be pretty slow (it has to build which means it has to
download dependencies in order to build). A few solutions:

* We could use nixpkgs (which lags the repo version by a few versions)
* We could use runx to install it (not nix, but it gets the latest
version)
* We could store in our own cache.

## How was it tested?

Tested running services on a few examples.
