Fix problem with wrong encoding of "+" character in Terraform runner

[Trojan295]

Description

I spotted an issue, where the "+" character was encoded as + in Terraform output e.g.

v1.20.5+rke2r1 instead of v1.20.5+ke2r1.

This was present in the output Argo artifact from the Terraform runner step, so most probably the issue is in the Terraform runner.

Expected behavior

+ characters in outputs from the Terraform runner should be encoded as +.

Actual behavior

+ characters in outputs from the Terraform runner are encoded as +.

Steps to reproduce

1. Run the cap.implementation.aws.containerization.rke.deploy Implementation.
2. Check the version in the output TypeInstance cap.type.containerization.kubernetes.cluster.
