fix: bump cache sqlite dbs to v2 for WAL journal mode change (#24030)

In https://github.com/denoland/deno/pull/23955 we changed the sqlite db
journal mode to WAL. This causes issues when someone is running an old
version of Deno using TRUNCATE and a new version because the two fight
against each other.
