doc: add repitition qualifier to version regexs

Currently the libuv version is reported as unknown on the
website. This is because the UV_VERSION_MINOR is no longer
a single digit and the regex is not getting a match for
the minor number. This commit makes the version regexs
capture multiple digit numbers.
