Changed this to use the just recipe

| uvx copier update --trust --defaults | ||
| # Do not update existing source files | ||
| uvx copier update --trust --defaults $(find src/{{ github_repo_snake_case }} -type f -printf "--exclude %p ") |

The problem was that running copier update ... deleted some files in the src/{{ github_repo_snake_case }} folder. Maybe because the folder name is templated?
In any case, there is a _skip_if_exists property in copier.yml, where you can set which files not to touch if they exist. Setting this worked for some test files I put in the folder, but interestingly not for __init__.py and py.typed. Even skipping all files in the folder didn't catch these two 🤔 .
The _exclude property is similar, but it stays in force regardless of the file existing, so a deleted file will not be recreated.
This version with the --exclude flag is a workaround: it excludes all files in the folder that exist, recreating the behaviour of _skip_if_exists in copier.yml. We could narrow it to only the two problematic files if this is too broad.
Any other ideas welcome!!

Otherwise copier will use a temp folder name it uses under the hood

github_repo defaults to the folder name. When updating, copier seems to keep the project in a temporary folder when it resolves the variables and ends up setting the name of this folder as github_repo. If we save the correct github_repo in the answers file, it will be read from there instead.
