Using mise edit generates config with invalid booleans

[issy]

Whenever I modify and save my config using mise edit, all the booleans get turned into eg " true", which causes subsequent mise commands to fail because the config is now invalid.

1 problem found:

1. mise is not activated, run mise help activate or
   read documentation at https://mise.jdx.dev for activation instructions.
   Alternatively, add the shims directory ~/.local/share/mise/shims to PATH.
   Using the shims directory is preferred for non-interactive setups.
