Fix 2025 broken cross-references (#1274)

Several 2025 changes created broken links within the WCA Regulations and
Guidelines, as references to removed Regulations and Guidelines were not
updated in other, otherwise unchanged, Regulations and Guidelines.

4b and 4f were merged with 4b remaining and 4f removed
([PR](#1212)). Previous
references to 4f need to be updated to 4b.

- 11e1+

4f+ was moved to 4b+
([PR](#1212)). A previous
reference to 4f+ needs to be updated to 4b+.
- 11e1+

E2b++ was removed, with its requirements now included in E6 and E2b2
([PR](#1228)). A previous
reference to E2b++ needs to be updated to E6 (the more relevant of the
two new regs).
