Not all CLI commands being documented

[tas50]

Describe the bug
When running: go run apps/gen-docs/main.go --docs-path ../docs/docs/cnspec/cli/. the following docs are generated:

_category_.json               cnspec_logout.md              cnspec_policy_lint.md         cnspec_serve.md
cnspec_framework_active.md    cnspec_migrate.md             cnspec_policy_list.md         cnspec_status.md
cnspec_framework_disabled.md  cnspec_policy_delete.md       cnspec_policy_upload.md       cnspec_vault_add-secret.md
cnspec_framework_download.md  cnspec_policy_disable.md      cnspec_policy.md              cnspec_vault_configure.md
cnspec_framework_list.md      cnspec_policy_download.md     cnspec_providers_install.md   cnspec_vault.md
cnspec_framework_preview.md   cnspec_policy_enable.md       cnspec_providers_list.md      cnspec_version.md
cnspec_framework_upload.md    cnspec_policy_format.md       cnspec_providers.md           cnspec.md
cnspec_framework.md           cnspec_policy_info.md         cnspec_run.md
cnspec_login.md               cnspec_policy_init.md         cnspec_scan.md

This does not match the commands from help:

In particular we need to make sure that vuln and shell are documented.
