fix: remove accented character in cell data

Description

Sprintcraft matches users between Jira and the opencraft.yml data by full name. Rômulo's name in Jira doesn't have the accented 'ô' because that made @-mentioning autocomplete more difficult in Jira. To fix matching his user, we can likewise remove the accented character from his name here.
