cabal init produces `extra-source-files: CHANGELOG.md`

[juhp]

Describe the bug
CHANGELOG.md(sic ChangeLog.md) (and README.md) should be listed as extra-doc-files not extra-source-files (see also #5813).

To Reproduce
Steps to reproduce the behavior:

$ cabal init --non-interactive

Please use version-prefixed commands (e.g. v2-build or v1-build) to avoid ambiguity.

Expected behavior
extra-doc-files: CHANGELOG.md

System information

• Operating system: Fedora
• cabal-3.2.0.0, ghc-8.6.5 versions

Additional context
extra-source-files: CHANGELOG.md is put in .cabal file.

Note that extra-doc-files is cabal-version: 1.18 (IIRC. please check) feature.

Okay but cabal init now produces cabal-version: 2.4 anyway, right?

Okay but cabal init now produces cabal-version: 2.4 anyway, right?

Interactive variant still could be selected to produce 1.10.

Gotya, good point!

I think you are right: #3825.
