fix(js): resolve VerdaccioWarning on the "logs" configuration property (#28234)

fix(js): resolve VerdaccioWarning: The configuration property "logs" has
been deprecated; Replaced with "log"

Currently, the Verdaccio configuration generated by running `nx generate
setup-verdaccio` contains the deprecated `logs` property. I have updated
this property to `log`, thereby removing the VerdaccioWarning that is
displayed when running `nx local-registry`

## Current Behavior
Currently, the Verdaccio configuration generated by running `nx generate
setup-verdaccio` includes the deprecated 'logs' property. When you run
`nx local-registry` Verdaccio displays the following warning:

## Expected Behavior
Run `nx local-registry` without the warning after using the
`setup-verdaccio` generator.
