Nominatim 4.5

[leonardehrenfried]

Nominatim 4.5 is moving to Python and the PHP part is now deprecated.

For that reason I removed PHP and apache.

I also upgraded to Ubuntu 24.04 which also uses Postgres 16.

Closes #584.

The CI configuration has been updated to consider a wider geographical region - shifting the focus from Rutland to England which could expand the relevance of the data analysis.

Again, this is just great! 😆

OTOH, this is quite good:

Three new scripts have been provided for managing various aspects of the application lifecycle - init.sh, start.sh, and startpostgres.sh. They broadly handle data file downloads, initialization of PostgreSQL database, performing initial data import, setting up the application, and monitoring application operations.

It looks like I encountered a bug in nominatim 4.5.0 when importing with --reverse-only: osm-search/Nominatim#3583
