[Ada] Fix markup in description of implementation-defined characteristics

[Ada] Fix markup in description of implementation-defined characteristics

[Pierre-Marie de Rodat]

[-- Attachment #1: Type: text/plain, Size: 402 bytes --]

Fix formatting of description lists, i.e. continuation lines are now
indented like their preceding lines.

Spotted while adding description of pragma Ada_2022.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* doc/gnat_rm/implementation_defined_characteristics.rst: Remove
	extra indent in continuation lines; indent both descriptions of
	Max_Picture_Length.
	* gnat_rm.texi: Regenerate.
