Remove double.fromEnvironment from dart-define doc (#124102)
Remove double.fromEnvironment from dart-define doc.
Fixes #124665
The current dart-define docs reads:
```
Additional key-value pairs that will be available as constants from the String.fromEnvironment, bool.fromEnvironment, int.fromEnvironment, and
double.fromEnvironment constructors.
```
while dart-define-from-file reads:
```
The path of a json format file where flutter define a global constant pool.
Json entry will be available as constants from the String.fromEnvironment, bool.fromEnvironment, int.fromEnvironment,
and double.fromEnvironment constructors; the key and field are json values
```
