Subject: [PATCH 2/2] docs: rust: clarify what 'rustup override' does

The behavior of 'rustup override' is not very well known. This patch is
a small edit that adds details about what it does, so users have a better
understanding of how it affects their system toolchain (i.e., it does
not affect system toolchain and only sets a directory-specific
override).
