Update legacy release notes links

[arnaucasau]

Part of #755

This PR changes the legacy release notes links to point to the qiskit 0.45 version folder.

How the change was done

I created a little script to transform every link in a release note file and re-write it in the same destination. I named it updateLinks.ts.

import { zxMain } from "../lib/zx";
import { globby } from "globby";
import { pathExists, getRoot } from "../lib/fs";
import { readFile, writeFile } from "fs/promises";
import transformLinks from "transform-markdown-links";

zxMain(async () => {
  const allVersions = (
    await globby("docs/api/qiskit/release-notes/[!index]*")
  ).map((releaseNotesPath) =>
    releaseNotesPath.split("/").pop()!.split(".").slice(0, -1).join("."),
  );

  for (const releaseNotesVersion of allVersions) {
    const source = `${getRoot()}/docs/api/qiskit/release-notes/${releaseNotesVersion}.md`;
    if (await pathExists(source)) {
      updateLinksFile('qiskit', releaseNotesVersion, source, source);
    }
  }
});

async function updateLinksFile(pkgName: string, versionWithoutPatch: string, source: string, dest: string) {
  let markdown = await readFile(source, { encoding: "utf8" });

  const regexAbsolutePath = new RegExp(
    "/api/" + pkgName + "/(?!release-notes)(?![0-9])",
  );

  markdown = transformLinks(markdown, (link, _) =>
    link.replace(regexAbsolutePath, `/api/${pkgName}/0.45/`),
  );

  await writeFile(dest, markdown);
}

To execute the script using npm run update-legacy-links you can modify the package.json file by adding the following line in the scripts section:

"update-legacy-links": "node -r esbuild-register scripts/commands/updateLinks.ts"

Awesome! There are still a lot of links to 0.46 in these release notes, which would be good to point to 0.45 instead. Those can be a simple find and replace for /api/qiskit/0.45/.

Also you can simplify the link checker toLoad logic.
