[Bug]: Inconsistency in naming

[Schiano-NOAA]

In the captions_alt_text.csv generated from running save_all_plots or just generally a function, the label name for some functions is inconsistent with the label made in the csv.

I am redesigning the asar::add_alttext() function so that it traces figures with their labels in the csv (this would be consistent with figures made in chunks rather than the rda structure as well).

The labels in the created csv will need to be checked against the labels made when asar::create_tables/figures_doc is run.

Note: I opened the issue in this repo, but either way the labels could be changed in asar instead. I think we should pick a simple naming convention that does not use acronyms.
