Error under electron: Adapter 'http' is not available in the build

## Expected Behavior
Used nano without errors under Node 20.4.0. I want to use the exactly same code under Electron that bundles Node 18.16.1

## Current Behavior
At the first call to nano
```
import Nano from "nano";
const nano = Nano({url: "my-CouchDB-url", requestDefaults: {timeout: 120_000}});
const databaseList = await nano.db.list();
```
I receive the error:
```
Adapter 'http' is not available in the build
```
Seems the error is generated by `axios` and seems the solution is to move to `fetch`. There is a possible workaround at https://github.com/axios/axios/issues/5523 but setting `agent` in the `requestDefaults` has no effect.

## Possible Solution
1) scrap axios and use fetch :-)
2) document a way to change axios adapter from outside. Agent option seems that does not change anything.

## Steps to Reproduce (for bugs)

1. Create an Electron application
2. In the main.js (that is, the Node process) add the lines listed above (putting a known CouchDB url).
3. Run `npm run dev`
4. See the error

## Context
Well, this problem blocks entirely my porting of the client-server application under Electron.
If there is no solution I have to scrap CouchDB and move to another DB.

## Your Environment

* Version used: 10.1.2
* Browser Name and version: Electron 26.0.0 that runs Node 18.16.1. Not run in browser.
* Operating System and version (desktop or mobile): Windows 11 64bits desktop
* Link to your project: Not public

Start with the Electron application's main.js and reproduce the failure by running npm run dev with the shown Nano configuration and a known CouchDB URL. Read how Nano passes requestDefaults to axios, including the adapter and agent behavior mentioned in the issue; done means nano.db.list() works under Electron 26 without the unavailable http adapter error.
