Add Lea Verou W3C TPAC travel request

[LeaVerou]

Sorry for the super late PR, turns out I had submitted my PR …in my own repo. 🤦🏽‍♀️🤣

Here's what I had written:

• TPAC is crucial for the TAG as it's the only chance to have meetings not just among ourselves, but jointly with other groups.
• Way smaller budget this time since ATH to SVQ is an intra EU flight, and have at least half of my accommodation covered, likely 100%.
• Budget should cover flights, non-covered meals, and ground transport and includes some wiggle room.
• This is my second TAG meeting this year,
• Last year I did not go to TPAC in Vancouver and joined remotely, saving OpenJS a transatlantic flight :)

@ljharb @eemeli @mcollina @tobie Came here to figure out reimbursement (1.5 month after TPAC 😅), saw this had not been merged. Could one of you please merge it?
