Support changing the endpoint of Octo STS for Self hosting

[suzuki-shunsuke]

Now the endpoint of Octo STS is hardcoded to https://octo-sts.dev/sts/exchange.

action/index.js

Line 42 in 3622e4d

const res2 = await fetchWithRetry(`https://octo-sts.dev/sts/exchange?scope=${scope}&identity=${identity}`, { headers: { 'Authorization': `Bearer ${json.value}` } });

To use this action with self-hosted Octo STS, we need to change the endpoint.
So how about adding an optional input variable endpoint to change the endpoint?
The default value is https://octo-sts.dev/sts/exchange.

e.g.

- uses: octo-sts/action@main
  id: octo-sts
  with:
    scope: your-org/your-repo
    identity: foo
    endpoint: https://example.com/sts/exchange

I think it maybe not enough as i saw octo-sts.dev hardcoded in octo-sts in quite many places.
