remove trailing commas and set consistent yaml width (#210)

# Summary
This pull request includes updates to improve YAML file handling and
fixes a minor issue in the `update_standalone` function. The most
important changes are grouped below:

### YAML Handling Improvements:
*
[`scripts/evergreen/release/helm_files_handler.py`](diffhunk://#diff-3e4bf7eb043336f19b2029c2f2b0c2d3497902c0b116255fc99fe6467ae1e453R81):
Added a new configuration to set the YAML line width to 4096 in the
`update_standalone_installer` function to prevent inconsistent line
wrapping in the CI and locally

### Bug Fix in Function Logic:
*
[`scripts/evergreen/release/update_helm_values_files.py`](diffhunk://#diff-362db66ba4c033cb3e6d12456bb89ac5782882ffc6f393e8f7d8d36b69aee0ffL60-R62):
Fixed the `update_standalone` function by removing trailing commas,
which were causing unintended behavior when calling the
`update_standalone_installer` function multiple times.

## Proof of Work

- consistent yaml formatting for linter (passing unit test variant)
