release tool: schema_descriptions not generated for `schema_descriptions_test`

[DaedalusG]

A migrator CI test (cmd/migrator:schema_descriptions_test) fails on releases when trying to reference schema-descriptions which aren't generated. See internal thread.

λ ~/sourcegraph/ publish-5.1.1* cat /private/var/tmp/_bazel_warrengifford/db322ce6c312cb7c2ca3c547ec29d0fa/execroot/__main__/bazel-out/darwin-fastbuild/testlogs/cmd/migrator/schema_descriptions_test/test.log

Missing entries would look like this:

        "schema-descriptions/v5.1.1-internal_database_schema.codeinsights.json",
        "schema-descriptions/v5.1.1-internal_database_schema.codeintel.json",
        "schema-descriptions/v5.1.1-internal_database_schema.json",

Fails at pnpm run release release:finalize in release process, currently the files entries are just added manually.

If you would like immediate help on this, please email [email protected] (you can still create the issue, but there are no SLAs on issues like there are for support requests).
