custom `writerOpts` `transform` no longer able to modify section titles

[Shereef]

Hello!

I have https://github.com/Shereef/release-notes-generator-issue repo to show the issue

When we have custom writer opts on v14 it is no longer able to modify the section titles (or anything for that matter)

You can see in the logs here:

[4:30:18 PM] [semantic-release] › ✘  An error occurred while running semantic-release: Error: Cannot modify immutable object.

}

This happens because in conventional-changelog-writer/dist/commit.js it calls the writer opts transform function with transform(preventModifications(commit), context, options) so when we try to modify it breaks

What is the new recommended way to do this?
