Replace YYYY-MM date with MM/YYYY or MMM YYYY

[SethFalco]

Seeing all the numbers together like that seems a bit cluttered. Instead we should use display month names or at least the abbreviated form?

Various references for this.

• Giraffe CVs - MMMMM YYYY or MMM. YYYY
• Resume Worded - MM/YYYY or MMM YYYY
• Jobscan - MM/YYYY or MMMMM YYYY

Workable advise specifying DD so that ATS systems can clearly see it's a date. However, most other sources don't offer the same advice, and some even discourage it as too much unnecessary information.

I'd prefer to avoid DD/MM/YYYY or MM/DD/YYYY as in most cases these are ambiguous anyway.

For now, I'll settle on MMM YYYY as I think it looks nicer.

While we're at it, let's also wrap dates in a time element and add the associated datetime attribute.
