Update warning in slider design patterns/fix broken link

[carmacleod]

The warning in the slider and multi-thumb slider design patterns needs to be updated to the latest wording from the new color slider example page.

Also, the Horizontal Slider Examples link in the slider design pattern needs to be changed from:
https://w3c.github.io/aria-practices/examples/slider/slider-1.html
to:
https://w3c.github.io/aria-practices/examples/slider/slider-color-viewer.html

and maybe change the link text to "Color Viewer Slider"?

I updated the warning message is both the thermostat and multithumb slider branches to match what is in color viewer slider.

This is about the warning note in the Slider Design Pattern itself in the aria-practices.html file.
I don't see that note updated in any of the slider PRs.

Here are the 2 Design Pattern links. They both have the old note:

• Slider Design Pattern
• Multi-thumb Slider Design Pattern

Also, the link in the first pattern still points to slider-1.html and it needs to point to slider-color-viewer.html.

I also noticed that you renamed "Horizontal Slider" to "Color Viewer Slider" in the examples/index.html (but not in aria-practices.html). You may want to change the aria-practices.html Design Pattern example links to have the new name and link.

Here are the links to Preview Links in PRs:

• Preview multi-thumb slider in PR#1758
• Preview slider thermostat in PR#1755

@jongund
I created PR #1803 to show what I mean. Please review! :)

I edited my previous comment because I forgot that the top-level filename was called aria-practices.html, and I was calling it index.html.

Note that after #1755 is merged, we will also need to update slider-2.html to slider-thermostat.html in aria-practices.html (and change "Three thermostat control sliders" to "Two thermostat control sliders"),

and after #1758 is merged, we will need to update multithumb-slider.html to slider-multithumb.html in aria-practices.html.
