Enhancement: Booktabs equivalent to "hlines" inner specification

[jw5801]

It would be excellent to have a "rules" inner specification which functions like the "hlines" specification but uses the booktabs top/mid/bottom rules instead.

That is, inserts a \toprule at the start of the table, \midrule between each row, and \bottomrule at the end.

For example:

\begin{tblr}{colspec={lll}}
  \toprule
  Row A & Row A & Row A \\
  \midrule
  Row B & Row B & Row B \\
  \bottomrule
\end{tblr}

Could instead be written as:

\begin{tblr}{colspec={lll},rules}
  Row A & Row A & Row A \\
  Row B & Row B & Row B \\
\end{tblr}

You may define a new tabularray environment:

\NewTblrEnviron{mytblr}
\SetTblrInner[mytblr]{hline{1,Z}={0.08em},hline{2-Y}={0.05em}}
