Rollup merge of #127434 - onur-ozkan:use-bootstrap-instead-of-rustbuild, r=Mark-Simulacrum

use "bootstrap" instead of "rustbuild" in comments and docs

Let's stick with the single name "bootstrap" to refer to the bootstrap project to avoid confusion. This should make it clearer, especially for new contributors.
