Decrypt with output-type dotenv panics on numbers #879
Description
Create a file test.yaml with just one key-value where the value consists of a number (i.e., integer or float). Plain decryption works fine:
$ sops --version
sops 3.7.1 (latest)
$ sops -d test.yaml
number: 123
$
The same call but using --output-type dotenv panics:
$ sops -d --output-type dotenv test.yaml
panic: interface conversion: interface {} is int, not string

It's the same when using a float (interface {} is float64, not string), or when using a JSON instead of a YAML file. I stumbled upon this while trying a sops exec-env with a Docker .env-file that contains a port setting.
