hugo: vendor modules before building page

Vendor hugo modules into `_vendor/` before building the page in release
mode (i.e. with `hugo`).

Reportedly, hugo tends to fail with odd errors along the lines of
"Permission denied" when trying to build the site, due to some weird
file permissions on the (elsewhere) vendored module files.

Testing has concluded that running `hugo mod vendor` before building the
page fixes this issue as far as I can tell. Adjust the build
instructions in the README.md file to reflect this oddity.
