Before users had to know the exact opacity that the MD/iOS spec called for in order to change the hover or focused background color. This allows them to change the background without having to know the opacity.
- changes apply to Action Sheet (Buttons), Back Button, Button, FAB Button, Item, Menu Button, Segment Button, Tab Button
- greatly reduces the requirement by users to set the background hover, focused states for dark modes and custom themes, also eliminates the need to know what the hover opacity is for each based on the spec
- updates the MD dark theme per their spec
- adds a component guide for internal use changing Ionic components

BREAKING CHANGE:
*Activated Class*
The `activated` class that is automatically added to buttons on press has been renamed to `ion-activated`. This will be more consistent with our `ion-focused` class we add and also will reduce conflicts with user's CSS.
*CSS Variables*
The `--background-hover`, `--background-focused` and `--background-activated` CSS variables on components that render native buttons will now have an opacity automatically set. If you are setting any of these like the following:
```
--background-hover: rgba(44, 44, 44, 0.08);
```
You will likely not see a hover state anymore. It should be updated to only set the desired color:
```
--background-hover: rgba(44, 44, 44);
```
If the opacity desired is something other than what the spec asks for, use:
```
--background-hover: rgba(44, 44, 44);
--background-hover-opacity: 1;
```
- adds support for changing the tag from `latest` to `next`
- checks the user's confirmation on the prepare and tag to end the script if the user selects no
- adds support for passing --dry-run to see what the publish will be
This changes the border into a linear gradient background image which allows us to avoid the height decrease on press and have the same border as the background color when pressed.
- merges all action sheet tests to the basic directory (except standalone, translucent), references #16715
- removes the height shift on press, fixes#16790
- fixes the cancel button on iOS so it is `#ffffff` by default
- gets the look of the action sheet closer to native for iOS
- only applies the translucent and backdrop filter if it is supported by the browser (chrome will not show transparent anymore)
- updates documentation to describe when translucent will show up
- adds documentation on how to use screenshot tests
