Overwritting existing models

[hboisgon]

HydroMT version checks

• I have checked that this issue has not already been reported.
• I have checked that this bug exists on the latest version of HydroMT.

Reproducible Example

hydromt update wflow wflow_piave -o wflow_piave_update -i update.ini -d artifact_data -vv

hydromt update wflow wflow_piave -o wflow_piave_update -i update.ini -d artifact_data --fo -vv

ERROR: Model dir already exists and cannot be overwritten

Current behaviour

When updating a model in an already existing folder, the models cannot be overwritten even with the --force-overwrite option on.

Desired behaviour

Like we implemented for build, I think if the user specifies --fo / --force-overwrite in update, hydromt should be able to overwrite the existing model.

Additional context

Doing a check below if force_overwrite then set root with mode="w+" and else keep mode="w"
