Update Lua to 5.4.8

[MisterSheeple]

Bug fix update

[ihaveamac]

Something in lcode.c was missed. (The other differences compared to 5.4.8 are indentation.)

Just to be sure, I copied 5.4.8's source to the repo and manually applied the patches in 9905b93 - these are the differences

Fixed, thanks! The indentation in those other files looks the same on my end though, and I'm not sure why.

[ihaveamac]

Tabs vs spaces; GodMode9 expects spaces.

[MisterSheeple]

Ah, thanks. should be fixed now.

[ihaveamac]

Looks good to me now. One last thing is to update README.md in the lua folder to mention 5.4.8 and then it's ready.

Thanks, both of you!
