Danger: suggest changelog change inline

[vaind]

Instead of the following, dangerfile could suggest specific update to the changelog, including the target file & line - that way, users can just apply the suggestion instead of manually going to the file.

🚫	Please consider adding a changelog entry for the next release.

Instructions and example for changelog

Please add an entry to CHANGELOG.md to the "Unreleased" section. Make sure the entry includes this PR's number.

Example:

## Unreleased

- hide `StackTraceMode` from options to avoid accidental errors when used with IL2CPP ([#1033](https://github.com/getsentry/sentry-unity/pull/1033))

If none of the above apply, you can opt out of this check by adding #skip-changelog to the PR description.
