Corrected configuration of exclude statements in pre-commit configuration

[JonathanWenger]

Description
Currently the pre-commit configuration assumes glob matching in the exclude statements, even though these are assumed to be regular expressions. This causes the exclude statements to match the wrong files and shows warnings when running pre-commit.

[WARNING] The 'exclude' field in hook 'flake8' is a regex, not a glob -- matching '/*' probably isn't what you want here
[WARNING] The 'exclude' field in hook 'ufmt' is a regex, not a glob -- matching '/*' probably isn't what you want here
[WARNING] The 'exclude' field in hook 'require-ascii' is a regex, not a glob -- matching '/*' probably isn't what you want here
[WARNING] The 'exclude' field in hook 'forbid-binary' is a regex, not a glob -- matching '/*' probably isn't what you want here

This PR replaces the glob statements with regular expressions in the pre-commit configuration.

This seems to be a common error and similar PRs have been made to other libraries (e.g. openml/openml-python#1129; cornellius-gp/gpytorch#2541)
