Docs: fix 'function "inner" not defined' in pruneEmptyDicts example

You will need to change your commit message and PR title to match our conventions. The prefix you would use is docs:.

The commit messages follow the conventional commits specification. chezmoi's release notes are generated directly from the commit messages. For trivial or user-invisible changes, please use the prefix chore:.

Ah, ok, sorry. Thanx for the info.

[halostatue]

Sorry; you need to fix both the commit title and the PR title.

The following command should fix this on your local clone of twpayne/chezmoi and push it up for review:

git commit --amend -m 'docs: Update pruneEmptyDicts example

Fix 'function "inner" not found' in pruneEmptyDicts example.
'
git push --force-with-lease

[FoolsTech]

Cool, thanx!

@FoolsTech the prefix needs to be lowercase (docs: instead of Docs:)

@halostatue
oh man, so sorry

[bradenhilton]

Thanks for the fix @FoolsTech!
