Starting a v2 container throws property not found: `tls-cert`, `tls-key`

A [user reported ](https://community.influxdata.com/t/influxd-config-path-is-completely-broken/33926/2) the problem below in Community and I can consistently reproduce it.

```sh
/home/runner/work/dasel/dasel/cmd/dasel/main.go:10 +0x24
Error: cannot use property selector on non map/struct types: invalid: property not found: tls-cert
Error: cannot use property selector on non map/struct types: invalid: property not found: tls-key
```

Note: While trying to troubleshoot, I removed all config files and was then able to run a container that didn't throw the `dasel` errors, and did throw the expected "missing TLS cert file" error. But, then after breaking it again, I wasn't able to repeat my "fix" by making the same changes.

Reproduced on my system.

OS: Mac OS X

In the following example, `$HOME/apps/influxdb-docker-files/data` and `$HOME/apps/influxdb-docker-files/config` are empty directories:

```sh
(env1) (base) ja@MacBook-Pro influx-docker-test % docker run \
-p 8086:8086 \
-v "$HOME/apps/influxdb-docker-files/data:/var/lib/influxdb2" \
-v "$HOME/apps/influxdb-docker-files/config:/etc/influxdb2-custom" \
-e INFLUXD_CONFIG_PATH="/etc/influxdb2-custom" \

```

Reproduce the supplied docker run command with empty data and config mounts, then trace how INFLUXD_CONFIG_PATH reaches the container startup and dasel invocation. Inspect the referenced dasel entry points, including cmd/dasel/main.go, context.go, value.go, func_property.go, and internal/command/put.go. Done means the v2 container avoids the dasel property errors and panic and reaches the expected TLS configuration error.
