BUG(?): commitDepth X gives you the first X commits, instead of the last X commits

[dansolhan]

Given a theoretical list of commits:

• This is the first commit
• This is the second commit
• This is the third commit
• This is the last commit

When using "commitDepth: 1", it seems that instead of getting the 1 latest commit, I get the first one.

Expected behaviour:
"commitDepth: 1" gives me: "This is the last commit"

Actual behaviour:
"commitDepth: 1" gives me: "This is the first commit"

Looking over this PR (https://github.com/wagoid/commitlint-github-action/pull/595/files) where the feature was implemented, it appears that it simply slices an array of commits (from, to), but my best guess is that the order of the original array was misunderstood to already be latest to earliest, rather than earliest to latest.
