Regex to catch a name and multiple groups with the same pattern

I have the following strings:

| Elencia   { 1: Simple one, 0: A longer sentence, or maybe not, 2: Another sentence }
| Elencia   { 10:    Sentence with spaces on left,     0: Same but with some spaces on right      }

I would like to catch the name on the left and the number + the sentence avoiding the multiple spaces on the left and the right.

I wrote this at the moment:

(?<point>[\d]+):\s+(?<content>[\w ]+)

but it only catches the part inside the curly brackets and it includes the spaces at the end, which is not what I want.

What I would like to have. First example:

- Elencia as name
- "1" as point, "Simple one" as sentence
- "0" as point, "A longer sentence, or maybe not" as sentence
- "2" as point, "Another sentence" as sentence

Second example:

- Elencia as name
- "10" as point, "Sentence with spaces on left" as sentence
- "0" as point, "Sentence with spaces on left" as sentence

I'm using the regex with gdscript but PHP or JavaScript style would work too.

Thank you for your help!
