ci: migrate Renovate config

[secustor]

Changes

Made some adaptions to the Renovate config:

• migrate packageRules away from removed options, to allow again grouping of services
• increase PR limit from 10 (default) to 20
• add PR label ( dependencies )
• do not extend base to prevent grouping by monorepos

Merge Requirements

For new features contributions please make sure you have completed the following
essential items:

• CHANGELOG.md updated to document new feature additions
• Appropriate documentation updates in the docs
• Appropriate Helm chart updates in the helm-charts

Maintainers will not merge until the above have been completed. If you're unsure
which docs need to be changed ping the
@open-telemetry/demo-approvers.

Hi @secustor 👋

• do not extend base to prevent grouping by monorepos

config:base was renamed to config:recommended a while back, so I'm only mentioning the new term config:recommended from now on.

If you like the config:recommended preset ¹, but don't want the grouping of monorepos, you might want to try the ignorePresets config option ². I think something like this would do what you want:

{
  "extends": ["config:recommended"],
  "ignorePresets": ["group:monorepos"]
}
