Adding longer prompts for all cookiecutter options

[matt-graham]

Fixes #296 and fixes #305

Adds longer human-readable prompts for all cookiecutter template options using the prompts field in cookiecutter.json (we already had a prompt for deploy_docs_to_github_pages option from #319).

Questions

• Do we want longer prompts for all options or do we think the longer forms for some of the more obvious ones like author_email are unnecessary?
• Do we want to set a maximum character length on the prompts? Some of the below are quite long which may cause them to wrap depending on terminal width.

With current prompts, creating a new packages with default options renders as

  [1/14] Given name(s) of package author (Eva Lu):
  [2/14] Family name(s) of package author (Ator):
  [3/14] Email address for package author - will be publicly accessible (eva.lu.ator@ucl.ac.uk):
  [4/14] Name for project - may contain spaces (Python Template):
  [5/14] 'Slugified' project name for use in URLs - recommended to be all lower case with hyphens as word separator (python-template):
  [6/14] Name for Python package - recommended to be all lowercase with underscores as word separator (python_template):
  [7/14] Short description of the project and package (A cookiecutter template with ARC recommendations.):
  [8/14] Initialise generated package directory as a Git repository [y/n] (y):
  [9/14] Enable automatically deploying HTML documentation to GitHub Pages website on pushes to main [y/n] (n):
  [10/14] GitHub user or organization which will be owner of repository if deploying to GitHub (eva-lu-ator):

    2 - 3.11
    3 - 3.12

I think this is a great idea. Agree on your second point, we probably want a character limit on them.

I've had a go at shortening the prompts - maximum character length is now 65, and renders as

  [1/14] Given name(s) of package author (Eva Lu):
  [2/14] Family name(s) of package author (Ator):
  [3/14] Email address for package author - will be publicly accessible (eva.lu.ator@ucl.ac.uk):
  [4/14] Name for project - may contain spaces (Python Template):
  [5/14] 'Slugified' project name for use in URLs - dash-case recommended (python-template):
  [6/14] Name for Python package - snake_case recommended (python_template):
  [7/14] Short description of the project (A cookiecutter package with UCL ARC recommendations.):
  [8/14] Initialise project directory as a Git repository [y/n] (y):

Some minor suggestions, but looks 👍 overall!
