docs(wiki): mark the 6.x pages historical, refresh the 7.x pages for 7.0.1 - the 20 pages describing the Bash implementation get a "Historical page (sr 6.x)" banner pointing at the current documentation; their content is untouched and nothing is deleted - the 11 topic pages generated from `sr help` are refreshed for 7.0.1: the Python floor is documented as 3.10 (the 7.0.0 pages said 3.9, which never actually worked in 7.x) and the generation footers carry the current version - Home and _Sidebar version stamps: 7.0.1
