Fix broken canvas dependency

[J053Fabi0]

The current code throws this error:

error: Uncaught SyntaxError: The requested module 'https://deno.land/std/encoding/base64.ts' does not provide an export named 'encode'
export { encode, decode } from "https://deno.land/std/encoding/base64.ts";
         ^
    at <anonymous> (https://deno.land/x/canvas@v1.2.2/deps.ts:2:10)

Updating the canvas dependency to the latest version solves the problem.

I have tested using import Graph from "https://raw.githubusercontent.com/J053Fabi0/DenoChart/main/mod.ts"; and it works.

These changes look good to me, aside from opting to use your jsr@deno-canvas instead of just bumping the version of the official one (https://deno.land/x/canvas@v1.4.1).

Why not just update this and deps.ts#L4 to https://deno.land/x/canvas@v1.4.1/mod.ts'?

That works for me:
