report_sample(): add indices names in caption instead of table

It would be nice to have the option of moving the indices names (Mean, (SD)) in a table caption (e.g., "Mean (SD) of each variable").

• First step is to be able to not write the indices (e.g., detail_indices=FALSE). As one can add the caption manually.
• Add an argument to add a caption (assuming the table is generated with insight's table system)
• Automatize the caption: not sure if that's worth the trouble though.

Since we mix mean/sd and proportions, how would you indicate the differences?
