chore: bump plugin versions in helm chart

[ahmad-ibra]

Prior to these changes, installing the chart via the following command returns some errors:

helm install validator ./chart/validator -n validator --create-namespace

Errors seen in validator-controller-manager:

Error: failed to fetch https://spectrocloud-labs.github.io/validator-plugin-vsphere/validator-plugin-vsphere-0.0.19.tgz : 404 Not Found

After making the changes we're able to install charts succesfully using the above command and all plugins also download.

Note that for now installing the chart via the helm repo also fails with the same errors, so we'll need to get a new version of the helm chart pushed after this is merged:

helm install validator validator/validator -n validator --create-namespace

@TylerGillson the tests are failing because of this error:

Error: failed to fetch https://spectrocloud-labs.github.io/validator-plugin-network/validator-plugin-network-0.0.14.tgz : 404 Not Found

Do you know why it would be trying to pull the chart from spectrocloud-labs?
