Rich Text images' alt text is not being recognized by "extract_strings".

[ho-tsl]

Hey there,

Currently, the extract_segments function does not recognize image alt texts inserted by a RichText block. This is an important accessibility issue that I would like your help to solve.

Is it possible to update the "extract_strings" function to extract these texts to be translated?

Hey @ho-tsl,

Feel free to give it a try. The segment extraction happens in

wagtail-localize/wagtail_localize/segments/extract.py

Line 237 in f5690d0

elif isinstance(field, RichTextField):

with the strings extraction in extract_strings as you point out.

It should be possible to do so. You may want to have a look at https://docs.wagtail.org/en/stable/extending/rich_text_internals.html#data-format for how Wagtail saves things like images/docs (and URLs) internally
