mismatch between installed package and package called in init to set the version

[IAlibay]

The cookiecutter sets the package name using cookiecutter.repo_name here: https://github.com/MDAnalysis/cookiecutter-mdakit/blob/main/%7B%7Bcookiecutter.repo_name%7D%7D/pyproject.toml#L9

but then sets the version using cookiecutter.package_name here: https://github.com/MDAnalysis/cookiecutter-mdakit/blob/main/%7B%7Bcookiecutter.repo_name%7D%7D/pyproject.toml#L9

In some cases cookiecutter.repo_name != cookiecutter.package_name (for example when @orbeckst created mdgeomkit, repo_name=mdgeomkit, and package_name=mdgeom). When this occurs the init version setter fails because it can't find the installed package.

I believe this was fixed in #115
