Fix list spacing between the marker and body workaround once Typst solves it

[jassielof]

At least for the APA template, the calculation is measured to eye. Basically, to avoid this:

#set list(
  marker: ([•], [◦]),
  indent: 0.5in - 1.75em,
  body-indent: 1.3em,
)

#set enum(
  indent: 0.5in - 1.5em,
  body-indent: 0.75em,
)

Where in APA it needs a 0.5in indentation (at least for first lines of a paragraph), but it's also inherited to the lists, and the - <VALUE> is a rough attempt at removing the marker width so the body indentation depends entirely to the margin.

This depends on typst/typst#4126 to be fixed first.
