This commit introduces the ability to skip the UI build in the Makefile by
providing prebuilt UI assets, addressing the needs of users who may not have npm
installed or who do not want to go through the front-end build process.
To achieve this, we added the `PREBUILT_ASSETS_STATIC_DIR` environment variable.
If this variable is set, the Makefile will skip the UI build and related tasks,
such as bundling npm licenses. Instead, it will use the prebuilt assets from
the specified directory.
We already publish prebuilt UI assets as part of our release artifacts
(e.g., `prometheus-web-ui-3.0.0-beta.0.tar.gz`). Users can download this tarball,
extract it, and point the `PREBUILT_ASSETS_STATIC_DIR` to the extracted folder.
This reduces build complexity, especially for users who don't have a development
environment for front-end builds.
For example, you can use the command:
`make PREBUILT_ASSETS_STATIC_DIR=static build`
where `static` refers to the directory containing the prebuilt UI files.
This change simplifies the build process while still allowing users to use a
prebuilt UI if desired.
This solution is particularly useful for users who don't need to modify the UI
and prefer to use the prebuilt version that we provide with each release.

Otherwise the resulting string depends on find, which afaict depends on
the underlying filesystem. A stable file list make it easier to detect
UI changes in downstreams that need to track UI assets.

This change makes sure that the git worktree is not changed while
compressing assets, making it better for local development.
To achieve this, the compression script keeps the un-compressed assets
and generates the go:embed directory when compressing the files.
A .gitignore file has been added to ignore generated files.

* Makefile: compress web assets before build
This commit add compression before (and decompression after) prometheus
is build. This ensures that gzipped assets are embeded in the prometheus
binary, if the builtinassets build tag is passed. If the build tag is
not passed this step is still executed but has no effect.
All this is executed in a subshell so that we can run the decompress
step even if the build step fails, but retain the exit code of promu.
This cleanup could also cover interrupts, but I left that out for now.
