[aggregate] Fix typos across codebase

[antoineco]

What is this for?

I suggest using this aggregate (editable by maintainers) as an effort to reduce the number of PRs dedicated to fixing (usually) small amounts of typos across the codebase, and therefore keep the commit history clean while preserving commits ownership by contributors.

I will myself try to spare time within the next few days and go through comments and documentation pages in order to fix as many typos as possible. I will keep aggregating new purely typo-related issues and PRs here.

Procedure

$ git fetch origin pull/<ID>/head:tmp-typo
$ git cherry-pick tmp-typo

Commits by the same author will be squashed before merging.

Aggregated issues/PRs

• Correct the returned message #2358
• Fix typo in lua script #2337
• Small typo fix in deploy/README.md #2297

@antoineco friendly ping

[antoineco]

@aledbf good that you remind me. I parked this after the massive changes to the documentation which invalidated 3 commits out of 5 :) Will push my changes package by package.

[antoineco]

@aledbf as changes to the cmd package are quite consequent (they do change user-facing strings) I opened a separate PR especially for these.

@aledbf I'd say this can be merged, there hasn't been a high rate of submission for typo-fixing PRs :)
