lua_rawget and lua_rawset expect tables

[Xmilia Hermit <xmilia.hermit@...>]

The Lua C API functions lua_rawget and lua_rawset expect a table which 
is used without any runtime check (except an API check) 
(https://github.com/lua/lua/blob/5d708c3f9cae12820e415d4f89c9eacbe2ab964b/lapi.c#L736). 
However, the manual 
(https://www.lua.org/manual/5.4/manual.html#lua_rawget) states for these 
functions that they are similar to lua_gettable which is not restricted 
to tables.
Since this seems not very clear 
(https://github.com/LuaJIT/LuaJIT/issues/810) it would be nice if the 
manual would make it clear for these two functions that tables are expected.
