Improve documentation of \with-dimension et al.
Right now the related command \with-dimensions
is documented here
https://lilypond.org/doc/v2.23/Documentation/notation/dimensions.html, however
no mention of \with-dimension
is made, which, as far as I can see, it's only
listed here https://lilypond.org/doc/v2.23/Documentation/notation/other. An
analogous point can be made about \with-dimension(s)-from
. Another similar
sounding command, \with-true-dimension
, is a bit more documented here
https://lilypond.org/doc/v2.23/Documentation/notation/other, however, it's not
obvious how to get there from anywhere in the documentation. One possibility
could be to add the corresponding links to
https://lilypond.org/doc/v2.23/Documentation/notation/dimensions.html.
