Add dedicated surface field for sport pitches

[Ambuj123554]

Description, Motivation & Context

Related issues

Closes #336

What this PR does

Creates a new surface_sport_pitch field specifically for leisure=pitch
presets. The field prioritizes common pitch surfaces at the top of the
dropdown instead of showing all surfaces alphabetically, improving the
mapping experience for sport pitches.

Changes

• Added data/fields/surface_sport_pitch.json — new field using
  stringsCrossReference to inherit all translations from the existing
  surface field, with options reordered by frequency of use on sport pitches
• Updated data/presets/leisure/pitch.json to use surface_sport_pitch
  instead of the generic surface field

Tested the surface field on a Sport Pitch — options now appear ordered
by pitch usage frequency with grass first, followed by artificial_turf,
asphalt, sand, concrete, clay etc. instead of alphabetical order.

Search

Searched "sport pitch" in edit mode — preset appears correctly with
the new surface field showing pitch-relevant surfaces prioritized.

I wonder how you arrived at these numbers (and the resulting order). When I go to taginfo, I get different results:

And I wonder why is it useful that the order (grass, artificial_turf, asphalt, sand ...) in the new field surface_sport_pitch differs from the statistics?

Sorry about that — I used older data when writing the description.
Checked taginfo again and you're right, the correct order by actual
usage should be grass, sand, asphalt, concrete, artificial_turf, clay,
paved, tartan, ground. Updating the options array now to match this.

[Ambuj123554]

@Hufkratzer @matkoniecz I've updated the options order based on the correct taginfo data and fixed the formatting. Would appreciate a review when you get a chance!

[Hufkratzer]

I like this order.

I would add woodchips at the end. We only have 185 pitch +woodchips in the database, but woodchips is also listed in the original surface field.

Perhaps the new field could also be used in the preset for leisure=track (?)

The additions to the field christian (babtist, ...) probablly do not belong to this PR, at least they are not explained above.

[Ambuj123554]

@Hufkratzer @matkoniecz I've addressed both points — removed the accidentally included christian.json changes and added woodchips at the end of the options list. Should be ready for review now!

[Ambuj123554]

@matkoniecz done — artificial_turf is now right after grass.
