Improve deprecation warning for Record.Value (#1015)

In partial assist for
#952.

Due to not having a reliable repro of #952, we update the deprecation
warning on Record.Value to be more explicit about updating to the new
field.

This pull request is blocked on the next bridge release as it needs
changes from
pulumi/pulumi-terraform-bridge#2746.
