Add "rm" alias for "uninstall"

[jsejcksn]

As a developer more regularly engaged with npm's command aliases, I would like a way to use the same kinds of shortened syntax with nvm. For example:

• npm i == npm install
• npm rm == npm uninstall
• etc.

It seems odd to me that nvm doesn't consistently use long- or short-form verbs for commands in the documentation. For example:

• nvm ls instead of nvm list
• nvm uninstall instead of nvm rm (nvm rm doesn't even work)

How can I get better command consistency with nvm? I'd be happy to consider working on PR for this, but I don't know where to start.

Have you tried these? nvm list and nvm ls both do the same thing (https://github.com/nvm-sh/nvm/blob/master/nvm.sh#L3171), as do nvm install and nvm i (https://github.com/nvm-sh/nvm/blob/master/nvm.sh#L2522), although uninstall has no aliases (https://github.com/nvm-sh/nvm/blob/master/nvm.sh#L2790).

Generally I'd say that destructive commands shouldn't be shortened - how often are you running nvm uninstall??

[jsejcksn]

@ljharb every time I update the current --lts or node release: I only keep installed the most current version of any major release, so every time there is a minor or patch update to any version that I have installed, I install the new version and uninstall the old one.

My voice is certainly only one of many, but perhaps the community at large agrees with me that rm is an appropriate alias for uninstall, especially given the other cited examples which are derived from the same origins?

Since npm uses i for install and rm for uninstall it'd make a lot of sense to use the same here.
