Add flag to obtain a Git remote link to a given zettel

[tpwo]

This command should be something like:

pyzet show --remote

And the output should be the full link to the zettel ID (e.g. 20220416171827) folder:

https://github.com/username/zet/tree/main/zettels/20220416171827

However, the construction of this link is different for different Git hostings. E.g. for Gitlab:

https://gitlab.com/username/zet/-/tree/main/zettels/20220416171827

or Bitbucket:

https://bitbucket.org/username/zet/src/main/zettels/20220416171827

One solution is to add a new field to the config file where the user can configure the base link for his hosting.

Alternatively, pyzet can parse the remote link and support some most popular choices (e.g. the three mentioned above).

Or, even better solution is to support the most popular platforms (with possible extending of them in the future) along with a new optional field in the config file that should be used for more niche hostings.

This will require some more work, but is probably worth it.
