Allow "Open Location..." of new GPX "download" link

[zstadler]

What steps will reproduce the problem?

In a browsr:

1. Open ​https://www.openstreetmap.org/user/CK@304HuK/traces/12284169
2. Copy the "download" link (​https://www.openstreetmap.org/traces/12284169/data)

In JOSM

3. "File" -> "Open Location..."
4. Paste the copied link
5. Click "Download URL"

What is the expected result?

The trace should be added

What happens instead?

JOSM shows a "Cannot open URL'​https://www.openstreetmap.org/traces/12284169/data'" error

Please provide any additional information below. Attach a screenshot if possible.

While JOSM accepts

".*(osm|openstreetmap).org/trace/\\p{Digit}+/data"

it does not accept a URL with "traces" rather than "trace". The pattern should be updated to

".*(osm|openstreetmap).org/traces\?/\\p{Digit}+/data"
