GitHub cards for repositories

[lazarusA]

closes #14

The core Card looks like:

<GitHubCard 
  name="WeatherGenenerator-Land"
  description="A Python package for generating synthetic weather data for land applications."
  language="Python"
  stars={42}
  forks={10}
  updatedAt="2023-10-01"
 href ="#"
/>

but all input arguments are fetched directly from the Github repos using

<DynamicGitHubCard 
  repoUrl="https://github.com/EarthyScience/WeatherGenerator-Land"
/>

which internally uses GitHubCard. See src/app/resources/software/page.mdx with live examples.
