feat(validateSingleCommit)!: check if the PR title matches the commit title

[kenji-miyake]

When we have a single semantic commit, even if we edit the PR title, it doesn't affect the squashed commit message. I think people usually don't want this behavior.

With this PR, we can ensure the PR title matches the commit title.

• Not match: feat: test(edited) kenji-miyake/action-semantic-pull-request#3
• Match: feat: test kenji-miyake/action-semantic-pull-request#4

@amannn I believe this will break the current behavior, so could you tell me how do you feel about it? Should I implement another parameter for this?

This is a fair point, thanks for the PR!

Honestly even if it can be seen as breaking, I feel like this just clears up confusion and makes the strange behaviour from Github a bit more transparent.

So personally I think we can get this merged in a minor release.

What do you think about a slightly more elaborative error message?

This update is breaking with dependabot.

Error: The pull request has only one (non-merge) commit and in this case Github will use it as the default commit message when merging. The pull request title doesn't match the commit though ("build(deps): bump amannn/action-semantic-pull-request from 3.6.0 to 4.1.0" vs. "build(deps): bump amannn/action-semantic-pull-request"). Please update the pull request title accordingly to avoid surprises.

It's fixed in v4.2.0
