Migrate to RavenDB v7

[andreasohlund]

Describe the suggested improvement

To stay updated

Additional Context

• Bump RavenDB.Embedded from 6.2.3 to 7.0.0 in /src #4774

[andreasohlund]

Updating in a minor is likely a breaking change so this would have to be done in the next major

[bording]

@andreasohlund Is there something specific in 7.0 that is making you think upgrading would require a major version?

EDIT:

Actually, 7.0 is not an LTS release for them, so we should not update to it at all: https://ravendb.net/support#endofsupport

[andreasohlund]

It was just base on a discussion with @ramonsmits that since we support external raven a major would be needed but not much thought went into that.

Actually, 7.0 is not an LTS release for them, so we should not update to it at al

Good catch
