Type mismatch when `make build`

[OlingCat]

I tried to make build PLFA and encountered the following error:

$ make build

Here is my building environment:

$ cabal --version
cabal-install version 3.10.2.1
compiled using version 3.10.2.1 of the Cabal library

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 9.4.8

$ agda --version
Agda version 2.6.3

This issue can be reproduced on Windows 11 and Archlinux/Ubuntu in WSL.

This can probably be fixed with an upper bound on the base64 package.

Fixed.
