Angular 19 upgrade

[HarelM]

We'll need to make sure angular 19 is supported.
I think we already did most of the migration stuff as part of version 18, but we'll need to check.
There's a question if we should support maplibre 5 with angular 18 or with 19 only to better address the breaking change that we did with maplibre 5.
I honestly don't know.

Maybe for some users would be great to have support for maplibre 5 with Angular 18. I think the breaking changes are relatively small which should still allow us to publish a version for angular 18.

Perhaps release maplibre 5 under 18.2 and the next major release will be in sync again with angular 19.

Too clarify the versioning between Angular/maplibre-gl and this library, we could add a version table to the readme:

Angular	maplibre-gl	ngx-maplibre-gl
18.x	>= 5.0.0	18.2.x
18.x	>= 4.5.2	18.1.x
18.x	>= 4.1.2	18.0.0

| Angular | maplibre-gl | ngx-maplibre-gl |
|:---:|:---:|:---:|
| 18.x | >= 5.0.0 | 18.2.x |
| 18.x |  >= 4.5.2 | 18.1.x |
| 18.x |  >= 4.1.2 | 18.0.0 |

I'll publish 18.2, the changelog should be enough in terms of compatibility I think, I'm not too keen on maintaining this kind of table...

[marcjulian]

Totally understandable. The changelog is fine for me too

18.2 was released.
Having said that, there's still a need to update the code to align with Angular 19 as part of this issue.
