Fix regression causing older versions of NotePad++ to crash (#13382)

Fixes regression caused by #13364
Closes #13397

Summary of the issue:
The version matching to apply the new NP++ 8.3+ behavior was incorrect, as it doesn't work for versions like 8.2.1 and 8.1.9.2.

Description of how this pull request fixes the issue:
Only match against the first character of the minor version.

Testing strategy:
Tested on version 8.1.9.2, 8.2.1, 8.3 and 8.3.1 of NP++
