TDT-2790 Clarify event visibility default is Google-only

[samLRodrigues]

What

Updates the KDoc for EventVisibility in src/main/kotlin/com/nylas/models/EventVisibility.kt to note that DEFAULT only works for Google events. Microsoft and EWS accounts return a 400 error when DEFAULT is sent, but the enum docs didn't warn about this.

Good afternoon! Thanks for tightening this up — the note is accurate and the provider-specific 400 behaviour is worth calling out. One thing before this ships: there's no entry under the Unreleased section in CHANGELOG.md. Please add a short line under Changed (e.g. "Clarify that event default visibility is Google-only") so the doc fix is tracked. Docs themselves look good.
