[UI] show - format verbose output args nicer

[omesser]

Suggest to display verbose options in a more friendly way (not single line)

Now:

❯ gto show -v
INDEX='artifacts.yaml' VERSION_BASE='tag' VERSION_CONVENTION='semver' VERSION_REQUIRED_FOR_ENV=True ENV_BASE='tag' ENV_WHITELIST=[] ENV_BRANCH_MAPPING={} LOG_LEVEL='INFO' DEBUG=False CONFIG_FILE='gto.yaml'
                 environment
          latest     staging production mystaging2 mystaging
features    None         NaN        NaN        NaN       NaN
nn        v0.0.1      v0.0.1        NaN        NaN       NaN
rf        v1.0.1      v1.0.1     v1.0.0        NaN       NaN
oded      v0.0.2      v0.0.2        NaN     v0.0.1    v0.0.1
