Fix ultimate trial/duo pro trial lead form phone number validation
What does this MR do and why?
Resolves #456330 (closed). The original pattern ^(\+)*[0-9-\s]+$ causes the browser to error out on invalid character class, specifically hyphen.
The problem exists in Chrome, Firefox and Safari. Fix works for all three browsers.
The test fails to capture this, possibly due to the limitation of different JavaScript environments: https://gitlab.com/gitlab-org/gitlab/-/blob/ed3e6e29e68093b34149f9bd186a39aea7c22c33/ee/spec/frontend/trials/components/trial_create_lead_form_spec.js#L84
