doc: replace --allow-fs-read by --allow-fs-write in related section
requested to merge github/fork/M1CK431/doc_replace--allow-fs-read_by_--allow-fs-write_in_related_section into main
Just notice a typo in the doc probably due to a copy/paste of the --allow-fs-read section into the --allow-fs-write section then forgot to rename some things.
