This commit aims to make guide wording on some pages more consistent to make it easier to understand.
A warning has been added above each Legacy Method page, and the links to their respective tools have been fixed.
HBL-Pichaxx: Changed DSiWare Dumper link to Frogtool, added note about 11.14, updated pichaxx injector link
HBL-Soundhax: changed 3.0.0 to 2.1.0 (the cart update section may need to be removed/reworded entirely as it is unclear...)
B9S-USM: Copied troubleshooting/QoL text fixes from HBL-USM; changed github link to LumaTeam
Legacy Methods: PicHaxx capitalization consistency
