Add new groups to Renovate configuration

[tamararivera]

Added new groups to the Renovate configuration:

• .NET packages
• IdentityModel packages
• OpenTelemetry packages

The rules use the regex configuration defined on their docs.

@tamararivera, if the intent of this grouping is specific to patches, should the config include "matchUpdateTypes": ["patch"]?
Also, why separate the identity packages? What is the reasoning behind it?

It's not supposed to be just for patches. I've pushed up a better name for the group.

Also, why separate the identity packages? What is the reasoning behind it?

The idea behind having multiple groups is so that things are grouped together when they release together. The Identity packages have a different release cadence, so they are grouped separately. I've also just added an OpenTelemetry group for those for the same reason.
