Support for different messages in commit messages and PR titles.

Why I Request This Feature

I want to use Gitmoji in my commit messages and here is my config.

The commit message is perfect:

But the PR titles are really ugly because :arrow_up: is not parsed (Maybe this is a bug of GitHub):

To prevent this, I expect Renovate to provide methods of setting different messages in git commits and PR titles, like commitMessagePrefix for commit messages and prTitlePrefix for PR titles.

Possible Changes

New config options:

key	type	default	description
prTitle	string	"{{{prTitlePrefix}}} {{{prTitleAction}}} {{{prTitleTopic}}} {{{prTitleExtra}}} {{{prTitleSuffix}}}"	Message to use for pull request titles.
prTitleAction	string	"{{{commitMessageAction}}}"	Action verb to use in PR titles.
prTitleExtra	string	"{{{commitMessageExtra}}}"	Extra description used after the pr title topic - typically the version
prTitlePrefix	string	"{{{commitMessagePrefix}}}"	Prefix to add to start of PR titles.
prTitleSuffix	string	"{{{commitMessageSuffix}}}"	Suffix to add to end of PR titles.
prTitleTopic	string	"{{{commitMessageTopic}}}"	The upgrade topic/noun used in PR titles

So it's possible to write something like this in the renovate config file:

{
    "commitMessagePrefix": ":arrow_up:",
    "prTitlePrefix": "⬆️",
    ...
}

When all prTitleXXXs are omitted, the PR title will be exactly the same as the commit message (current behaviour).

❤️ Thanks!

So you want emoji for commit messages but Unicode for PR titles?

This isn't possible via config alone - will need a new feature - so I'm moving this issue to the main repo
