Subject: [PATCH] feat(medusa-js): add axios adapter to config (#6214)

**What**

- Adds the ability to pass an Axios adapter through the client's config.

**Why**

- When using NextJS with the edge runtime for deployment on Cloudflare Pages, for example, Axios does not work. Therefore, it is necessary to pass an adapter like [@vespaiach/axios-fetch-adapter](https://github.com/vespaiach/axios-fetch-adapter).

**How**

- Receives the **axiosAdapter** in the config and implements it when creating the **axiosClient**.

Closes #6133
