FIX openmaptiles/openmaptiles#1319

Concurrently with PR openmaptiles/openmaptiles#1320

Use updated lake_centerlines.geojson. (#390)

Revert to Python 3.9 (#389)

Tools in 6.0 used Python 3.8.  The 6.1 tried to upgrade to Python 3.10, but the [py-ascii-graph](https://github.com/kakwa/py-ascii-graph) is not compatible (used by the `test-perf` tool). Reverting to Python 3.9 should fix it for now.

Fix auto-publish workflow build error (#388)

Use docker --pull by default, bump to python 3.10 (#386)

Use docker build --pull by default, unless NO_REFRESH=1 is set
(this is the same param as in the primary OMT repo)

Also, upgrade to the latest stable Python ver 3.10

fix incorrect mode message in import-osm

Per @Falke-Design suggestion, fixing incorrect messaging

Add helpText to requires (#373)

Add `helpText` to `layer.requires` like discussed in openmaptiles/openmaptiles#1220

I had to change from `SELECT 'osm_ocean_polygon'::regclass;` to `PERFORM 'osm_ocean_polygon'::regclass;` because plpgsql needs a return value if `SELECT` is used.

Also added an error if a function has no arguments:
```
when invalid_text_representation then
        RAISE EXCEPTION '%! The arguments of the required function "osmFunc" of the layer "water" are missing. Example: "osmFunc(text)"', SQLERRM;
```

Example:
```
layer:
  id: "water"
  requires:
    helpText: 'This is a text with "quotes"'
    functions: "osmFunc"
    tables: "osm_ocean_polygon"
```

SQL:
```
-- Assert osm_ocean_polygon exists
do $$
begin
        PERFORM 'osm_ocean_polygon'::regclass;
exception when undefined_table then
        RAISE EXCEPTION '%! This is error text with "quotes"', SQLERRM;
end;
$$ language 'plpgsql';

-- Assert osmFunc exists
do $$
begin
        PERFORM 'osmFunc'::regprocedure;
exception when undefined_function then
        RAISE EXCEPTION '%! This is a text with "quotes"', SQLERRM;
when invalid_text_representation then
        RAISE EXCEPTION '%! The arguments of the required function "osmFunc" of the layer "water" are missing. Example: "osmFunc(text)"', SQLERRM;
end;
$$ language 'plpgsql';
```

Result of `make import-sql`:
> psql:/sql/parallel/water__waterway.sql:10: ERROR:  relation "osm_ocean_polygon2" does not exist! This is a text with "quotes"
