runtime(nginx): highlight Lua in set_by_lua_block in syntax script

The set_by_lua_block directive of the Lua module takes an additional
variable as an argument which currently breaks the detection of inline
Lua blocks. For example:

set_by_lua_block $myvar {
return tonumber(ngx.var.myothervar)-1
}

closes: #19362
