fix: minor typo and grammar adjustments

[G-Rath]

Noticed one when working on #318, and figured might as well run my IDE spell-checker on the project - this will also mean I'm a contributor so don't need first-time approval for CI on future PRs.

The changes look good, thanks! Were these typos spotted with an IDE plugin or some built-in feature? Is this available in VSCode?

There's something going on with Github Actions. Git clones fail randomly - even in actions/checkout.

I'll check the CI again later and merge once successful.

Yeah I use IntelliJ, which has a NL spellchecker called Grazie.

Apparently they were having an incident, which has now been resolved 🎉
