Beautify docsy site page

[jpolton]

Landing page for documentation is not very informative: https://british-oceanographic-data-centre.github.io/COAsT/

rename the landing page buttons to where they link to

[thogar-computer]

I think this page https://british-oceanographic-data-centre.github.io/COAsT/about/ also needs rework

[thogar-computer]

anaconda section could link to the coast package
Twitter section either points to a COAsT twitter page or is removed.
Contributions welcome section should be updated to make it clear that it links to the documentation repo

see https://british-oceanographic-data-centre.github.io/COAsT/#td-block-1

https://british-oceanographic-data-centre.github.io/COAsT/community/

This then points out to the pypi version (should we also include the anaconda links here)

[thogar-computer]

https://british-oceanographic-data-centre.github.io/COAsT/docs/getting-started/getting-started-at-liverpool/ <- should this be in the wider public documents

look to see if docsy can be update in backend (is there new feature/bug fixes)

@jpolton , I update the website template. Could you please take a look at this video to check if you want to change anything?

I've made several enhancements to the website, including:

1. Adjusted the title font for better readability.
2. Revised the banner background by adding opacity to improve its legibility with text overlaid.
3. Streamlined the "about" and "community" pages, transferring all relevant information to the main page. Navigation links in the navbar now guide users to specific sections based on their corresponding "id."
4. Removed all references to Docsy for a cleaner and more tailored look.
5. Introduced fresh content related to the project, with the possibility of offering more comprehensive descriptions of the package's features and capabilities in the "About" section.
6. Included license information in the footer of the website.
7. Regarding the "Getting Started at Liverpool" section, I've removed it from the documentation. I've created a temporary page on the NOC Intranet and added this link to the "Getting Started" page. Please note that we may need to update this link in the future.
8. As I made some modifications to the Docsy theme, I've copied certain Docsy partials to the main repository, specifically the footer and header.
9. Additionally, I've included new CSS classes and images in the repository's assets. Some adjustments to the Docsy CSS were necessary to implement these changes effectively.
10. I also updated the install instructions on the README file.

All looks great.
Perhaps the COAsT/README needs a review, (with a new ticket)?

I created the pull request here British-Oceanographic-Data-Centre/COAsT-site#95

I will merge these updates into the develop branch
