Update vue-router to latest (OSOE-945)

[Piedone]

vue-router v4 brought breaking changes that the module needs to be adapted to. See version details here and migration docs here.

• Open an issue branch from the branch of Update dependency vue-router to v4 #79.
• Fix any compatibility issues.
• Use ConstantFromJson from Helpful Libraries instead of hard-coded versions in ResourceManagementOptionsConfiguration.
• Remove the temporary "All packages" group from renovate.json5.

After merging the issue branch, the Renovate PR should close itself.

@barthamark @sarahelsaig perhaps something you'd be interested in?

@barthamark @sarahelsaig?

I'm a bit swamped with other tasks right now and not really an expert with vue-specific updates lately. If @sarahelsaig don't want to work on it, then I can take a look in 1-2 weeks.

1-2 weeks can work.
