Add SpatialData & squidpy tutorial to Analysis tools

[Zethson]

• Consider renaming analysis frameworks and tools to data structures and frameworks
• Ensure that the existing content still runs with the latest versions (https://www.sc-best-practices.org/introduction/analysis_tools.html)
• Iterate through the existing text. Is it understandable to you?
• Are there ways to reduce the content? Anything that we explain that should not be there?
• Add an advanced section for https://spatialdata.scverse.org/en/stable/
• Add an advanced section for https://squidpy.readthedocs.io/en/stable/ that ideally uses SpatialData
