fix(github): Sanitize mentions in commit bodies

[zharinov]

Changes

Although GitHub doesn't render Markdown in the commit bodies, the mentions are triggered anyway.

Users can configure Renovate in such a way changelogs are rendered in the commit body, which may cause undesired notifications for GitHub users mentioned in the changelogs.

This PR fixes the problem by adding zero-width space after every occurrence of @ character.

@zharinov @rarkins @viceice could it be that this now causes strange Chinese characters to appear in commit messages (displayed in Github and TortoiseGit)?
I am now facing such commit messages
in TortoiseGit

and Github

using renovate 38.44.2 (via renovatebot/github-action).

I guess it's because the zero-width space is interpreted as "舃" in these locations.

@ceisele-r plesse start a new discussion then link here. Can you reproduce it on GitHub.com or it needs specific local settings?
