Why are we removing these post-build checks from build-builder-alpine?

Ah well, I guess we could keep the checks if we want - they were added previously because I was pulling the sample builder and wondering, what could possibly be going on?
Thinking about this more, the alpine builder in its current state (without --buildpack overriding the order) is actually broken 😞 for demo purposes which is not ideal. I think I will simplify the tutorial (and make the builder working by default) by introducing a BP_ environment variable to control the Hello Extensions buildpack behavior WRT extensions.
TLDR; I'll update this PR and create a corresponding docs PR to make everything better

Added the aforementioned improvements in cc5328a and buildpacks/docs#571
…nd failed the build by default (as it requires tree, which is not installed on the builder) Now, the buildpack will opt-in to the build only if a build-time environment variable is set Additionally, it can be made to require dependencies through the environment, instead of having to edit the /bin/build script Signed-off-by: Natalie Arellano <narellano@vmware.com>

…e deploying We are currently overriding the builder that was just built by using --pull-policy=always when using the builder in a build This will be fixed in #142 but we can't merge that one until the pipeline is green Signed-off-by: Natalie Arellano <narellano@vmware.com>

In CI a `pack build` is performed using one of libcnb's example CNBs and the upstream `cnb/sample-builder:alpine` builder, in order to test that our static MUSL compile works with non-libc base images. However, CI has just started failing with: ``` ERROR: failed to build: experimental features must be enabled when builder contains image extensions ``` (https://github.com/heroku/libcnb.rs/actions/runs/5530837180/jobs/10090742723?pr=592#step:10:107) This is due to the upstream images having been rebuilt with extension support, which is an experimental feature until the next stable Pack CLI release): buildpacks/samples#149 buildpacks/samples#142 As such until Pack CLI v0.30 is released as stable, we'll have to pin to an older `alpine` image by SHA256 ref. GUS-W-13746154.

We need --pull-policy=always when the builder contains extensions (the builder must exist in a registry so that we can pull the manifest)
However pulling the remote builder overrides the locally built one, making our test useless and causing us to re-publish the builder that was already in Docker Hub
Spinning up a local registry should solve the problem
