Install bundled Quarto extensions into current working directory and create
new qmd using skeleton documents. This function extends a function written by
Thomas Mock: https://github.com/jthomasmock/octavo/blob/master/R/use_quarto_ext.R
and by Spencer Schien: https://spencerschien.info/post/r_for_nonprofits/quarto_template/.
This is equivalent to the quarto command quarto use
with a --template
flag.
