Documentation: some commands are missing '-' in `git-cliff`

[KennyLorin]

Is there an existing issue for this?

• I have searched the existing issues

Description of the bug

Having a look at this page of documentation, the following line is missing the '-' between git and cliff:

git cliff --init

In both this file and others, there is a mix of git-cliff and git cliff.

For cases where git is not available in the environment, this leads to unknown commands when copy/pasting.

It does not look like git-cliff needs git to work, i.e. when I run git-cliff -u it does read the contents of the commits successfully.

Steps To Reproduce

The following dockerfile was used:

FROM alpine:3.23.3

RUN apk add git-cliff

Then running:

/app $ git cliff 

returns

sh: git: not found

Expected behavior

Either:

• indicate that git is required for git-cliff to work ("getting started" or "installation" page)
• or ensure all example commands contain the '-'

I'll add that this is really not a high-priority bug at all since I can both add the '-' myself or install git in the given container, this is more for QoL than anything.
