to, hopefully, get rid of the following error:
```
2022-02-13 13:32:12 [ERROR] Failed to get [GITHUB_TOKEN]!
2022-02-13 13:32:12 [ERROR] []
2022-02-13 13:32:12 [ERROR] Please set a [GITHUB_TOKEN] from the main workflow environment to take advantage of multiple status reports!
```
The 'slim' version drops certain storage-heavy linters[0] which we don't
use anyway, so let's make the job a bit faster by downloading and using
a smaller image.

Judging by
ERROR! Failed to call GitHub Status API!
it doesn't seem to work. Even if it did it would just clutter the status
checks I think so let's just remove MULTI_STATUS along with
GITHUB_TOKEN.
some actions like Coverity and CFLite aren't run on every PR so to make
sure they are more or less fine when they are changed it makes sense to
at least check them with superlinter/actionlint: https://github.com/rhysd/actionlint
The following warnings were fixed along the way:
```

```
to let Dependabot keep track of them using SHAs
codeql-actions doesn't point to SHAs because it isn't clear
whether Dependabot supports their release cycle mentioned
at https://github.com/github/codeql-action/issues/307
