Allow to specify the output format of func version via --output

[creydr]

Changes

• 🎁 Allow to print the output from func version as json or yaml too (in case of json/yaml, it will always be verbose output)

$ func version   
v0.47.0-68-g05a4aa8b

$ func version -v
Version: v0.47.0-68-g05a4aa8b
Knative: v1.20.0
Commit: 05a4aa8b
SocatImage: ghcr.io/knative/func-utils:v2
TarImage: ghcr.io/knative/func-utils:v2

$ func version -v -o json
{
  "version": "v0.47.0-68-g05a4aa8b",
  "knative": "knative-v1.20.0-68-g05a4aa8b",
  "commit": "05a4aa8b",
  "socatImage": "ghcr.io/knative/func-utils:v2",
  "tarImage": "ghcr.io/knative/func-utils:v2"
}

$ func version -o json   
{
  "version": "v0.47.0-68-g05a4aa8b",
  "knative": "knative-v1.20.0-68-g05a4aa8b",
  "commit": "05a4aa8b",
  "socatImage": "ghcr.io/knative/func-utils:v2",
  "tarImage": "ghcr.io/knative/func-utils:v2"
}

/kind enhancement

This can be useful, when we want to add the latest middleware versions in the output of func version too.

Hint for reviewers:

The main change is in 83c736e (and 4b0265c). d5fd435 was only a refactoring moving the Version struct to the version.go file. Thus the whole PR can be a bit "noisy".

Release Note

Allow to print the output from `func version` as `json` or `yaml` too

You may need to adjust tests.

Just did it in 4b0265c. Not sure, why it had an empty line at the end before 🤷
