Docs for 0.26 features

Remove the RAW_TABLE FK reference to METABASE_DATABASE

Fixes #5866

Make purple button text white on hover instead of blue

Remove the double encoding of the collection's slug

Add type information to expression columns

Fixes #5108

Expressions aren't columns, but they have an entry in the cols
property which currently doesn't have type info. This adds that which
allows it to be used as the Y-axis in graphs.

Fixes #3952

Render pulse even if pulse channel is missing `details` prop

Fix typo in the no-preview-display analyzer

Add to the overview section of the timezone troubleshooting docs

Fix new databases being not included in the permissions grid

Fixed a typo or two, moved one sentence, and replaced "timezone" with "time zone" throughout to match the rest of the file.

Fixup human readable values when field values change [ci drivers]

Field values and human readable values are zipped together to support
remapping. If the field values change (i.e. new values, removing
values etc) then the pairings of those field values and their remapped
values can be wrong. This commit adds some code to reconcile that. If
a new field value is found, a stringified version of that field value
is used as the human readable version (the user can update/change this
later).
