fix: support LuaJIT versions with neovim 0.9.2 and 0.10.x (#518)

neovim 0.10 has bumped up LuaJIT version, which makes plenary.profile
fail to work due to the "LuaJIT core/library version mismatch" error.
We can have an allowed range for `jit.version_num` as 20100~20199.

FYI, `require('jit')` reports:

  nvim-0.9.1:
    version = "LuaJIT 2.1.0-beta3",
    version_num = 20100

  nvim-0.10.x (HEAD version as of today, an example):
    version = "LuaJIT 2.1.1693268511",
    version_num = 20199
