Bugfix: Replace Node20 execution handler with Node20_1 for ReplaceTokens task

[tiredofchoosing]

Reason

Node20 execution handler is no longer supported in latest versions of azure-pipelines-agents (v3.x and v4.x, for example 4.268).

There is an error when executing pipelines with the latest version of the ReplaceTokens task:

Description  : Replaces tokens in a file using RegEx. Values come from any variable defined in the current Environment.

Workaround for Azure DevOps pipelines and self-hosted agents:

Manually update task.json file in downloaded (cached) version of the task in the agent folder agent\_work\_tasks
