Please update documentation for H5Provider - axiosConfig vs axiosParams

[vedina]

Describe the bug

According to June 15, 2022 commit H5GroveProvider no more accepts axiosParams , but the documentation is not updated

To Reproduce

Go to https://github.com/silx-kit/h5web/blob/main/packages/app/README.md

<H5GroveProvider
  url="https://h5grove.server.url"
  filepath="some-file.h5"
  axiosParams={{ file: 'some-file.h5' }}
>
  <App />
</H5GroveProvider>

The demo app is indeed up-to-date

<H5GroveProvider
      url={URL}
      filepath={filepath}
      axiosConfig={{ params: { file: filepath } }}
    >
      <App sidebarOpen={!query.has('wide')} getFeedbackURL={getFeedbackURL} />
    </H5GroveProvider>
