fix: Add missing * value

[Derugon]

Issue

Some parameters accept one or multiple string values, such as ApiBlockParams.pagerestrictions.
For example, all following calls are valid:

• api.post( { action: "block", pagerestrictions: "Foo", ... } )
• api.post( { action: "block", pagerestrictions: ["Foo", "Bar", "Foo Bar"]], ... } )

And a few of these parameters alternatively accept a * value (equivalent to a list of all possible values), such as ApiBlockParams.namespacerestrictions.
For example, all following calls are valid:

• api.post( { action: "block", namespacerestrictions: 2, ... } )
• api.post( { action: "block", namespacerestrictions: [2, 3, 11], ... } )
• api.post( { action: "block", namespacerestrictions: "*", ... } )

However, this * value is currently not included in interfaces.
For example, the current definition of ApiBlockParams.namespacerestriction is:

export interface ApiBlockParams extends ApiParams {
    namespacerestrictions?: namespace | namespace[];
    ...
}

Proposed changes

This information is provided by a allspecifier property in a module parameter. This PR allows its use as a single value.
For example, the definition of ApiBlockParams.namespacerestriction becomes:

export interface ApiBlockParams extends ApiParams {
    namespacerestrictions?: namespace | namespace[] | "*";
    ...
}
