Integrate spell checker into GitHub workflows

[viachaslavic]

Add typos-action for changed files in PR's . Exceptions can be added to the _typos.toml config file.

The current implementation of this action will display found errors in the workflow log. I think to wait for an update with a code suggestion in Sarif format.

Could help #297

@viachaslavic Should be good now that Sarif report has been integrated in Typos ?

Thank you.

@gouchi Yes, the format itself is implemented, but I was thinking of waiting for integration into github-action so that a comment with the spell checking result would be automatically added to pull requests.

In fact, you can already merge it without this feature. In which case the results can be viewed in the annotations by going to Typos Action (for example, as in this PR)

@fpscan We should merge this PR ;)

Thank you.
