meta: Release and launch geospatial support for DuckDB

[lostmygithubaccount]

Acceptance criteria: Geospatial operations are supported for DuckDB, the default backend. This brings a great local option for small-to-medium geospatial data processing in Ibis.

TODOs:

• geospatial implementation
• initial geospatial blog
• dev guru geospatial blog
• add an example for geospatial data
• improve docstrings for geospatial operations

Weekly Update:
2024-01-18

• Second geospatial blog was released: docs(blog-post): replicate spatial dev guru blog ibis#7973, and also publicized in social media. (twitter, linkedin, and reddit)

At the moment we do have support for 30+ geospatial functions, but we are lacking of better documentation, this two issues are meant to tackle that problem:

• feat: add an example geo dataset to ibis.examples ibis#7958
• docs: add example docstrings to geospatial methods ibis#7959

This PR just got merged, which to support geospatial literals on duckdb, which will make creating examples that are more compelling:

• feat(duckdb-geospatial): support for literals ibis#7975

No update here as this is complete. What do we want to do with this epic? Maybe a tag to mark it as completed, or edit the title and add [completed]

let's go with [DONE] in the PR title, I've done that for now here -- might come up with something better later
