Fix opinionator

[josephjclark]

We've had a security alert from a low level dependency (word-wrap), which comes out of optionator.

The vulnerability affects two packages: salesforce and mailgun.

Salesforce is actually a red herring because it only affects a dev dependency, which I have corrected here (and has since been fixed on main). I've also removed yargs from salesforce deps as its unneeded.

For mailgun I have overridden the version of optionator. If you install mailgun now and run npm why optionator, you can see that the version is correctly overridden:

Note that adding the override in the monorepo root (via pnpm) doesn't actually affect the built packages (disappointing but on reflection perhaps not surprising). So we have to do it in the adaptor itself.

This is a good workaround until we properly update the mailgun package.

Note that this is based on the pnpm bump branch.

Closes #330 (and the associated vulnerabilities)

@mtuchi I've just rebased this on top of the other changes

I think the changes in salesforce/package.json reverts back what was done in this PR #337

We should remove them since they are already done

Thanks for being vigilant @mtuchi !

I've checked out the package.json from main and removed yargs. It should be up to date now.

This looks good now, i am going to merge it
