fix(material/datepicker): remove fixed width as not working on mobile

[ajitsinghkaler]

In date picker the events example is not responsive on mobile because it has fixed width now changed it to max-width

[mmalerba]

@ajitsinghkaler I would also be fine with just removing the width/max-width completely. I don't think it's really necessary.

I see that you just added the pr: merge ready label, but the following checks are still failing:
     status "ci/circleci: api_golden_checks" is failing
     missing required labels: target: *

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.

[mmalerba]

The API golden checks is just something that was broken at head for a little while, this PR is fine

[ajitsinghkaler]

@mmalerba I've made the change can you please look into the request now.

[ajitsinghkaler]

@mmalerba now what do I have to do to get the checks right.
