Chart generation failure during OSS version-bump PR build

[airbyte-jenny]

Current Behavior

https://github.com/airbytehq/airbyte/runs/4230816560?check_suite_focus=true
Upon requesting a version bump, a PR is created automatically, and a build begins. During that build, "Generate Docs Parameters" fails on the step "Test can update README with generated parameters" with the error:

##[debug]Loading env
Run ./ci.sh check-docs-updated
  ./ci.sh check-docs-updated
  shell: /usr/bin/bash -e {0}
##[debug]/usr/bin/bash -e /home/runner/work/_temp/fa8da9bb-d636-42db-a8e6-d1d840c76603.sh
Error: no repositories to show
Error: looks like "https://charts.bitnami.com/bitnami" is not a valid chart repository or cannot be reached: stream error: stream ID 1; INTERNAL_ERROR
Error: Process completed with exit code 1.
##[debug]Finishing: Test can update README with generated parameters

This prevents the build from completing.

Expected Behavior

The build completes normally without error.

This is fixed now.
