Use shorter commands by default

[shizhMSFT]

Human beings are lazy to type. It is better to default to shorter command names

• repository --> repo
• list --> ls
• show-tags --> tag

Basically, the alias and command names should be swapped.

I think show-tags should be tags.

Yes, it's tags. My typo.

Since list becomes unix style ls, it is better to rename delete to rm

• oras manifest delete --> oras manifest rm
• oras blob delete --> oras manifest rm

Since we rename delete to rm, it is better to rename --yes to --force to be consistent with the unix command rm.

Additionally, since oras manifest fetch has an alias get, we should also have an alias get-config for fetch-config.

According to Remove -vs- Delete,

Remove and Delete are defined quite similarly, but the main difference between them is that delete means erase (i.e. rendered nonexistent or nonrecoverable), while remove denotes take away and set aside (but kept in existence).

manifest / blob delete are indeed delete. Hence, we should keep the delete for the correct wording and uses rm just for alias.
