Check docs for all scanners for correctness: WPScan

Part of the effort to sanity-check all documentation.

Scanner Sanity-Check:

Sanity Check if the existing documentation is understandable and useful for you as a (first time) user
Ensure the general chart/scanner description is up to date and consistent to other scanners
- ./scanner/NAME/.helm-docs.gotmpl -> {{- define "extra.chartAboutSection" -}}
Ensure the baseline scanner configuration is up to date and consistent to other scanners
- ./scanner/NAME/.helm-docs.gotmpl -> {{- define "extra.scannerConfigurationSection" -}}
Ensure there is at minimum one scan example with the following files:
- Example Scan File: ./scanner/NAME/examples/EXAMPLE-NAME/scan.yaml
- Example Scan Result File: ./scanner/NAME/examples/EXAMPLE-NAME/findings.yaml
Ensure the docs files are generated correct and are up to date (sometimes the automated helm-docs update via SCB-Bot failed to update the docs correctly)
- ./scanner/NAME/readme.md
- ./scanner/NAME/docs/README.ArtifactHub.md
- ./scanner/NAME/docs/README.DockerHub-Parser.md
- Optional, only if a dedicated scanner image is defined:./scanner/NAME/docs/README.DockerHub-Scanner.md
