fix: use the correct allowed char ranges for fabric mod ids (#1104)

### Motivation
The current fabric platform generator is generating invalid mod ids due
to a too permissive mod id description in the fabric wiki.

### Modification
Ensure that the mod id is matching the actual mod id pattern
`[a-z][a-z0-9-_]{1,63}` of fabric (taken from the
[MetadataVerifier](https://github.com/FabricMC/fabric-loader/blob/2a378f1c563b6ec96ae6620a278ecd23fa09da0f/src/main/java/net/fabricmc/loader/impl/metadata/MetadataVerifier.java#L36))

### Result
Mod ids for fabric are now generated correctly and no longer cause a
startup crash.

##### Other context
Fixes #1102
