Small updates to dataset list

[hotzenklotz]

This PR adds a few changes to the dataset list in the dashboard:

• remove the isActive and isPublic columns to save screen space
• changes to Allowed Teams column:
  • the isPublic information is now available in the Allowed Teams column
  • renamed the Allowed Teams column to Access Permissions, which I found more self-explanatory. Feedback welcome.
  • added antd table filter for Access Permissions, e.g. to filter a publicly shared dataset
  • restricted tag width and added ellipsis for long names
• changes to data layers column:
  • changed the displayed tags from layer category to layer names as suggested by @normanrz , e.g. "color" --> "axons"
  • added antd table filter for data layer, e.g. to filter for all datasets with "synapse" layers/information
  • restricted tag width and added ellipsis for long names
• Changes to tags column:
  • switched from a fixed width column to using max-width. In cases with no tags, the whole table should be narrower.

URL of deployed dev instance (used for testing):

• https://___.webknossos.xyz

Steps to test:

• Test access permission column filters
• Test data layers column filters
• create some long team names
• create some long tags
• filter for public dataset (set one to public first)

Issues:

• None
