CLI panics when trying to deploy bundle

[agagrins]

Describe the issue

When running in CircleCI with a Docker image cimg:python3.11, and doing databricks bundle deploy --force-lock, the CLI panics

Steps to reproduce the behavior

1. docker pull cimg/python:3.11
2. docker run --rm -ti --mount type=bind,source=./bundle.yaml,target=/home/circleci/project/bundle.yaml,readonly cimg/python:3.11
3. curl -fsSL https://raw.githubusercontent.com/databricks/setup-cli/main/install.sh | sudo sh
4. databricks bundle deploy --force-lock

Expected Behavior

The asset bundle should be deployed

Actual Behavior

The asset bundle is not deployed

OS and CLI version

Docker image cimg:python3.11 and latest CLI version. It's the same for Python 3.10, and for several other images

Is this a regression?

Seems to be same same for v0.299.0, v0.298.0, and v0.297.2. Versions before that fail with the openpgp: key expired error. But yes, this whole thing used to work

Debug Logs

The specifics of the bundle config have been redacted

The Databricks CLI unexpectedly had a fatal error.
