chore(NA): assure bazel bin is available on kbn clean and reset commands

[mistic]

One step forward on #69706

@timroes reported that clean command failed if we don't have Bazel installed before running it. While I was expecting, by the time you run clean or reset in a branch using Bazel, a bootstrap was already run I believe we should add a safeguard here.
