annotate required flags in docs

[lovromazgon]

Description of change

Inspired by @hariso comment I created this PR, which adds the string "(required)" to the docs of all required flags. It also removes the suffix "(default 10s)" from the timeout flag, since that's automatically added by cobra.

I did not update the docs yet as I want to first make sure we actually want to do this.
Documentation is changed: https://github.com/meroxa/meroxa-docs/pull/45
