brace tables with typst:no-figure and typst:text attributes (jgm#10563)

The combination of jgm#9648 Typst property output and jgm#9778
`typst:no-figure` can cause fonts to spill out of tables.

This is because setting Typst text properties across a table
requires `set text(...)` outside the table, and previously we
were relying on the figure to provide a scope.

This adds an extra `#{...}` when the table has class `typst:no-figure`
and also has `typst:text:*` attributes.
