feat(forge fmt): add hard-tabs / tabs instead of spaces as configuration in [fmt] #10754
Description
Component
Forge
Describe the feature you would like
It would be nice if the foundary.toml [fmt] section included the ability to use tabs instead of spaces.
Additional context
Indentation spacing is typically a stylistic or accessibility choice of the individual engineer, rather than the project itself. Tabs allow individual engineers to designate the tab_width in their own personal editor preferences without affecting other team members with different needs or preferences.
This likely shouldn't be turned on by default, as tabs vs spaces is an age-old internet debate, but it would be great if there was an option available for the teams that would like to use them.
