[REQ][PowerShell] Add additional reserved words list for parameter name in PowerShell

Created by: SimeonGerginov

An additional reserved words list is added for parameter name in PowerShell. The initial reserved words list contains all reserved words provided by PowerShell. However for the parameter name, only the variables extracted in the new list can't be passed as names of a PowerShell Advanced function parameter. With the additional reserved words list, keywords like Filter don't receive the additional prefix Var when they're parameter names.

Closes #8805 (closed) @wing328

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh
  ./bin/utils/export_docs_generators.sh

  Commit all changed files. This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master. These must match the expectations made by your contribution. You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*. For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master, 5.1.x, 6.0.x
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.
