Support for --ignore-missing

[dscdac]

Hey,

In the last Sentry-cli version they this --ignore-missing option so it doesn't break when Sentry cannot figure the current or last commit. I faced this kind of issues when deploying from Github Actions for some reason (even when checking out with fetch-depth: 0).
Would be cool to add it as an option in the Webpack config.

Cheers!

I've created a 'placeholder' for how the code would look like:
master...dscdac:ignore-missing
Unfortunately, the new --ignore-missing option is not included in the Sentry-cli types:
