Maintainer-filed docs cleanup to strip core18 from non-release docs once Snapcraft 9 is stable (now true: 9.0/9.1 are current). Triaged and volunteer PR #6292 open, but core18 references remain in specify-a-base, list-extensions, change-bases and example recipes.

Suggested action: keep open

Reason: The issue is labeled 'Status: Triaged' and authored by maintainer medubelko, and its stated trigger has since occurred: docs/release-notes/index.rst now lists Snapcraft 9.0/9.1 as current, so core18 docs are stale rather than premature. Work is actively in flight — munlicode commented 'I would love to work on this' and opened PR #6292 — but that PR is still open and unmerged after ~101 days with the author's support-chart questions unanswered, and grep confirms residual core18 references in docs/how-to/crafting/specify-a-base.rst, list-extensions.rst, change-bases/change-from-core18-to-core20.rst and four integrations example recipes. Scope is somewhat ambiguous (the support chart intentionally depicts core18's ESM/Pro lifecycle, and the core18-to-core20 migration how-to may need deletion rather than editing), which lowers actionability and keeps complexity mid-range rather than trivial.

Issue body

### Check existing issues - [x] I've verified that this request isn't described by any existing issues. ### Request When Snapcraft 9 is made stable, core18 won't be officially supported anymore. At that time, we'll need to comb through the docs and remove references to it outside of release information. ### Document location _No response_
