False Positive Warning for Valid Cron Expression

[minhqdao]

Describe the bug
The YAML validator is showing a diagnostic hint/warning (blue squiggly line) although a valid cron expression is used.

To Reproduce
Steps to reproduce the behavior:

1. Use this workflow:

name: Cron

on:
    schedule:
        - cron: "*/15 * * * *"

jobs:
    say_hi:
        runs-on: ubuntu-latest
        steps:
            - run: echo "hi"

2. Observe warning

Expected behavior
No warning.

Extension Version
v0.28.2

It's actually an info which explains the cron setting, not warning.

The blue squiggly line more or less breaks the UX convention. Guess it's for promoting the functionality. Maybe only a hover on effect is needed.
