chore: Bump esbuild-loader 2.14.0 -> 2.15.1

Changelog:

* https://github.com/privatenumber/esbuild-loader/releases/tag/v2.15.1
* https://github.com/evanw/esbuild/blob/v0.12.28/CHANGELOG.md

This allows us to remove the hack we introduced in
git #tuleap/stable/a23aca9fdb3c90ecb83eb1a29a19c23f7f02f9ab
(due to evanw/esbuild#1538)

No functional changes
