call BrowseX with 1 arg for patch >= 9.1.1485

vim/vim@ef92555

patch version checked with git tag --contains ef92555 in vim repository.

netrw#BrowseX() was changed in Vim patch 9.1.1485 to take a single argument and handle remote detection internally. Use one-arg call when that patch is present, and fallback to the old two-arg form for older builds.

Would it be feasible to check the version in g:netrwPlugin_loaded instead?

Do you mean g:loaded_netrwPlugin? If so, that’s what I initially considered too.
However, in patch 9.1.1486 the value of g:netrwPlugin_loaded is still v181, so users building Vim from that patch will get an incorrect function usage.
Additionally, patch 9.1.1484 also v181, so the variable does not accurately indicate the behavioral change introduced in 9.1.1485.
