Remove env.configFilePath and env.secretsFilePath

These utilize `.Files.Get` in Helm
Per the Helm docs (https://helm.sh/docs/chart_template_guide/accessing_files/):
> Some files cannot be accessed through the .Files object, usually for security reasons.
> Files outside of a Helm application subchart, including those of the parent, cannot be accessed

Because of this, `.env.configFilePath` and `env.secretsFilePath` are only ever usable if you have a copy of this repo in your local directory when installing. When installing the Helm chart through the https://helm.releases.hashicorp.com release, because the chart is pulled from the HashiCorp repo, these files are not considered a part of the chart, causing `.env.configFilePath` and `env.secretsFilePath` to always be a no-op.

This has caused confusion on a support ticket, so I propose we remove these two values entirely.

Examples/proof:

Working because we edit the chart itself (install `.`)
```bash
echo 'TFE_HOSTNAME: "testing"' > env-config.yaml
helm template tfe . --set "env.configFilePath=`pwd`/env-config.yaml"
```

Not working because we are pulling from the HashiCorp repo
```bash
echo 'TFE_HOSTNAME: "testing"' > env-config.yaml
helm template tfe hashicorp/terraform-enterprise --set "env.configFilePath=`pwd`/env-config.yaml"
```
