Issue number: N/A
---------
<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->
<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->
## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
In addition to migrating away from `toMatchSnapshot` as found in PRs
such as https://github.com/ionic-team/ionic-framework/pull/28083, I
think it would be valuable to have a lint rule to prevent developers
from accidentally using this API in the future.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Adds a lint rule which errors if `toMatchSnapshot` is being used in
`*.e2e.ts` files.
## Does this introduce a breaking change?
- [ ] Yes
- [x] No
<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->
## Other information
<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->
~Note: This PR's lint step will continue to fail until the remaining
`toHaveScreenshot` migration PRs have been merged. Do note merge this PR
until that has been completed.~ All set!
