fix: build manually the app binary for codeql

[rach-id]

Overview

Currently, the auto builder doesn't support go version 1.21.1, and it expects the binary to be built using make instead of make build. This PR installs the right version of go manually and builds the binary.

https://github.com/celestiaorg/celestia-app/security/code-scanning?query=pr%3A2645+is%3Aopen shows errors so I think CodeQL is working after this PR.

It's not immediately clear from the PR description what was broken with CodeQL before this PR but I'm guessing the auto build here didn't work. Can you please confirm @sweexordious ?

[rach-id]

yes, I'll update the description
