fix typescript annotations

[omarkhatibco]

I was getting some errors from the typing, so I fixed it.

node_modules/@yimura/scraper/index.d.ts:10:1 - error TS1046: Top-level declarations in .d.ts files must start with either a 'declare' or 'export' modifier.

10 const Constants = {
   ~~~~~

node_modules/@yimura/scraper/index.d.ts:10:19 - error TS1254: A 'const' initializer in an ambient context must be a string or numeric literal or literal enum reference.

10 const Constants = {
                     ~
11   SearchTypes,
   ~~~~~~~~~~~~~~
12   YoutubeURL: URL.prototype,
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
13 }
   ~

node_modules/@yimura/scraper/index.d.ts:11:3 - error TS2693: 'SearchTypes' only refers to a type, but is being used as a value here.

11   SearchTypes,
     ~~~~~~~~~~~

node_modules/@yimura/scraper/index.d.ts:92:10 - error TS1040: 'async' modifier cannot be used in an ambient context.

92   public async search(query: string, options?: SearchOptions): Promise<Results>;
            ~~~~~

Thanks for your contribution, I don't use TypeScript so I rely on community contributions for typescript annotations.

I will merge it into master and try to publish it asap.
