Use mdc-theme-primary for buttons

[naofireblade]

Version of HACS

0.21.6

Describe the bug

Buttons in dialoges (e.g. for restarting home assistant after HACS update) should use the same styling as home assistant buttons (e.g. for restarting from server settings).

Currently HACS uses primary-color as button background and primary-text-color as font color. This results in unreadable buttons in some themes (e.g. my clear-theme-dark):

The home assistant default for these buttons is a transparent background and mdc-theme-primary as font color.
