clear example.nu (resolves #23)

[AucaCoyan]

I deleted a bunch of commands that VS Code threw me a warning.

In the process, I realized there are a couple of issues in other parts of nushell:

• from eml and another sister commands aren't core anymore, but docs are in the nushell site
• same with from parquet
• g command doesn't have a help text when you press g and tab in the nu commandline
• there may be some missing flags in the http patch help menu (like -H for example)
• touch -d doesn't exist in windows, idk if nu in other OS has it, or if its native in another os

• nu_plugin_formats has from eml, from vcf, from ini, and from ics
• nu_plugin_from_parquet is here https://github.com/fdncred/nu_plugin_from_parquet. I eventually will add it to nushell. I just haven't yet.
• g is an alias for dirs goto, if you do help goto you'll see the help. you're right that it doesn't show up. I guess that's a papercut and not quite done yet.
• If you run the code I pasted your issue about this, you should have all the examples and hopefully there's an example with each flag, but i'm not sure.
• I think -d for touch was removed altogether.

i get the following

Error: nu::shell::external_command

  × External command failed

because the bits commands have been removed from the default feature of nu and now live in extra 🤔

It's better to make a new file I guess. Because example.nu is script-generated, we shouldn't assume it will be constant over time.
I would rather create another file. What do you think?
The PR is available to re-open 👍🏼
