Standards checklist:

• The PR title is descriptive.
• The PR doesn't replicate another PR which is already open.
• I have read the contribution guide and followed all the instructions.
• The code follows the code style guide detailed in the wiki.
• The code is mine or it's from somewhere with an MIT-compatible license.
• The code is efficient, to the best of my ability, and does not waste computer resources.
• The code is stable and I have tested it myself, to the best of my abilities.
• If the code introduces new aliases, I provide a valid use case for all plugin users down below.

Changes:

Aliases for the following commands

• jj bookmark - Aliases for bookmark subcommands
• jj git push - Aliases for popular push flags
• jj status - well, alias for just that

See commit itself for the list of actual aliases.

Other comments:

I am keeping these aliases in my custom jj-extra plugin and find them handy in day to day work. I think upstreaming them is good thing. If for any reason this won't be desirable I'll be happy to maintain a separate jj-extra plugin.
