boards: ti: lp_em_cc2340r5: Fix documentation

[jpanisbl]

This ensures board shows up nicely in docs and search.

Implement the changes requested by @kartben : #76441 (review)

[jpanisbl]

@kartben I implemented the changes you requested but the CI fails it seems:
Key 'full_name' was not defined. Path: '/board/socs/1'.: Path: '/'>

Should I finally remove this line ?

[UPDATE] Actually I found the issue. full_name is not exactly where it should -> Fixed now

Great, thanks! Too bad the image is apparently not using a transparent background, missed that during initial review.

I will try to change that while updating the Supported Features chapter of the documentation, when the other drivers will get upstream too. :)
