Implement top-bar navigation for relevant BioJulia packages

[M-PERSIC]

Is your feature request related to a problem? Please describe.
A top-bar would serve to both categorize and highlight relevant packages (link to their documentation pages) that are either part of the BioJulia ecosystem or are crucial for common biology applications.

Such packages should be included based on their relevance in their respective domain as well as their overall quality, to-be-determined by the community.

Describe the solution you'd like
SciMLDocs renders a top bar via MultiDocumenter.jl. I am also tracking native top-bar navigation support for Documenter.jl

It might be of interest to include sub-categories with packages grouped according to subject (biology, biochemistry, genetics, ecology,..) as well as whether they are considered third-party, meaning outside of BioJulia.

A draft outline in no particular order

• Core
  • Sequencing libraries (BioSymbols,...)
• Modelling
  • Simulations (EcoSISTEM,...)
• Analysis
  • Plots and Visualization (BioMakie,...)
• Research
  • Bibliography (Bibliography.jl,...)
  • Packages involved in research projects (J-SPACE,....)
• Developer Tools
  • File support (XAM,...)
  • Extra resources (workshops, recorded conferences,...)

Describe alternatives you've considered
Top-bar navigation seems optimal in this instance. If, for whichever reason, a top-bar cannot be implemented, we could simply highlight/categorize relevant packages in a new page.
