fix(eslint-plugin): no-explicit-any constructor functions (& more) not ignored by ignoreRestArgs property

[N2D4]

Previously, the following were not ignored by the no-explicit-any rule if the ignoreRestArgs property was given:

declare class A { f(...args: any[]): unknown; } // AST_NODE_TYPES.TSEmptyBodyFunctionExpression
type T = new (...args: any[]) => unknown // AST_NODE_TYPES.TSConstructorType
type T = {new (...args: any[]): unknown} // AST_NODE_TYPES.TSConstructSignatureDeclaration
type T = {f(...args: any[]): unknown}; // AST_NODE_TYPES.TSMethodSignature
declare function f(...args: any[]): unknown; // AST_NODE_TYPES.TSDeclareFunction

This PR fixes that.

The code sample in the docs is now a little long, I'll shorten it if needed
