- Switched to use bookworm Python image as `curl` is not in slim.
- Use `pre` tags for console blocks. We lose syntax highlighting, but
get rid of the copy button.
- Fix `dockerfile` tag in tutorial.
- Fix GitHub typo in README.
- Extract README sections into BUILDING and CONTRIBUTING documents. This
should work better than sections in README as it keeps the README short,
and the BUILDING and CONTRIBUTING files will stand out in the file list.
- Merged localdev document into BUILDING.
- Fixed broken links.
- Changed DNS setup so later DNS-dependent steps should work.
- Added h1 and link to SECURITY document.
