[Dialog] Dialog don't follow M3 specs

[neo-xy]

Bug report

Dialog background is not following M3 sepcs-> should be surface-container-high but it's not.
(if it should not follow - can we know the reason why?)

Steps to reproduce

Issue first was reported here: angular/components#29230
but angular-components team "linked" it here.
!!! If corrected please inform Angular-components team about it !!!

Actual behavior

background is of different color then specified in docs (much more lighter)

Expected behavior

background should be set to surface-container-high as per docs: https://m3.material.io/components/dialogs/specs
which is the one thta is used in M3 Figma components

Your Environment:

Software	Version(s)
MDC Web
Browser	Chrome
Operating System	MacOs

Possible solution

Change dialog bg to be set to surface-container-high and Inform Angular-components team about it
(I am guessing that You are using "old" veriation of "surface" colors so the issue may exists in other components as well)

I think this lib is M2 only

the M3 web components are found at https://github.com/material-components/material-web
