Previously the buildpack's S3 bucket was defined in two places - once in `VENDOR_URL` and again during the pip installation step. This duplication was necessary since `VENDOR_URL` also contained the stack's name, whereas the pip use-case used a non-stack-specific S3 key prefix. In order to: * reduce this duplication * simplify this buildpack's S3 bucket migration (where we'll soon be needing the vary the bucket name and wouldn't want to have to duplicate that logic in multiple places) * allow overriding of the URL for the pip use-case ...the `VENDOR_URL` variable has been replaced with `S3_BASE_URL` which no longer contains the stack name. The user-configurable override has similarly been renamed from `BUILDPACK_VENDOR_URL` to `BUILDPACK_S3_BASE_URL`. Note: As before, this override cannot be set via standard app variables (see #989). The unused `USE_STAGING_BINARIES` environment variable has been removed, since it's a leftover from the project to stand up a staging S3 bucket. It's redundant given the `BUILDPACK_S3_BASE_URL` variable. Closes @W-8142401@.
