Python and Quarto versions out of sync

[rstub]

The Python and Quarto versions referenced in the chart are not those that are present in the default Docker image:

helm/charts/rstudio-connect/values.yaml

Lines 434 to 447 in 400de4a

	Python:
	Enabled: true
	# Note: The `Executable` listed below are only used for Local Execution.
	# For Off-Host Execution, Python versions are defined by the set of Execution Environments
	# https://docs.posit.co/connect/admin/python/
	Executable:
	- /opt/python/3.12.11/bin/python
	- /opt/python/3.11.13/bin/python
	Quarto:
	Enabled: true
	# Note: The `Executable` listed below is only used for Local Execution.
	# For Off-Host Execution, Quarto versions are defined by the set of Execution Environments
	# https://docs.posit.co/connect/admin/quarto/
	Executable: "/opt/quarto/1.4.557/bin/quarto"

For rstudio/rstudio-connect:ubuntu2204-2026.01.1 this should read:

  Python:
    Enabled: true
    Executable: /opt/python/3.13.9/bin/python
    Executable: /opt/python/3.12.11/bin/python
  Quarto:
    Enabled: true
    Executable: /opt/quarto/1.8.25/bin/quarto

This is an issue when Launcher/off-host execution is not used.
