This PR is to update the token version to v6.1.
* This version fixes https://github.com/flutter/flutter/issues/153271
* Change the chip default border color from `ColorScheme.outline` to `ColorScheme.outlineVariant`. The Chips' border color is softened to improve visual hierarchy between chips and buttons
This PR is to
* Update the Material Design tokens to 5.0.0
* 4 color roles in **Light mode** have different default values
`onPrimaryContainer`: Primary10 -> Primary30
`onSecondaryContainer`: Secondary10 -> Secondary30
`onTertiaryContainer`: Tertiary10 -> Tertiary30
`onErrorContainer`: Error10 -> Error30

* new tokens added in list.json
* `md.comp.menu.list-item.*` tokens are deprecated and should be replaced by tokens in list.json and we've done the migration last year:)!(#122388)
This PR is to update material tokens to the latest version 4.1.0, which:
* deprecates two tokens in `Slider`
* doesn't impact the material widgets' defaults
This PR is to
* Update the Material Design tokens to 4.0.0
Since the last token update(#145356), only `Slider` tokens have been updated. The M3 `Slider` has significant visual changes, compared to the original M3 Slider, so a separate PR would be needed. I commented out `SliderTemplate` and added a TODO when we are ready to add new widgets again.
* Updated the Material Design tokens to v2.3.5
* Linear and circular progress indicator token sets are deprecated in v0.207. The `md.com.progress-indicator` token set was created and should be used instead.
* tokens is now using [semantic versioning](https://semver.org/) ï¼Thanks @guidezpl for reminding:) )
* ~Fixes #128877. The default text style is updated to `bodyLarge` now:)~ Added TODOs for the label text style of `PopupMenuButton`. Will create a separate PR because this change breaks Google testing.
