435: fix(scripts/helm-docs): ignore dependency helm charts when generating README.md r=niladrih a=niladrih

The script `/scripts/helm/generate-readme.sh` generates documentation for all charts present inside the `/chart` directory. The `helm-docs` tool recursively walks through all charts in the directory and generates docs for them. This is inconvenient if there are dependency charts inside the `/chart/charts` directory. We don't necessarily want to add documentation for these charts to the README.md The `-g` option disables this.
```console
-g, --chart-to-generate strings    List of charts that will have documentation generated. Comma separated, no space. Empty list - generate for all charts in chart-search-root
```
