Description

We are using redb in iroh-dns-server. The recently released redb v3 has incompatible changes to the database format. The recommended upgrade procedure is to upgrade the database with Database::upgrade on redb v2.6+. The upgrade has to be done on redb v2, not v3. See https://github.com/cberner/redb/blob/master/CHANGELOG.md#removes-support-for-file-format-v2.

This updates redb to 2.6 and performs the upgrade when opening the database. Calling upgrade on an already upgraded database is a no-op.

With this merged in the next release, we can then update redb to v3 in the version after.
