Update ~/.enso/credentials file

[MrFlashAccount]

Pull Request Description

This PR updates the content of ~/.enso/credentials file, where we store jwt token.
Now the content would look like this:

{
  "client_id": <id>, <- this is cognito app integration client id
  "access_token": <token>, <- jwt generated for current session
  "refresh_token": <token2>, <- refresh token taken from initAuth flow
  "refresh_uri": <token> <- "https://cognito-idp.eu-west-1.amazonaws.com/"
  "expire_at": <iso datetime> <- datetime when the access token will go expire
}

Closes: enso-org/cloud-v2#934

We had a conversation with @radeusgd, this PR will be merger after @radeusgd adapts the parser for the new format.

mostly nits

what's the difference between this and new Date(expirationTimestamp * 1_000) btw?

[MrFlashAccount]

The result is the same, just used to write that way. Not sure which solution is better though.

[somebody1234]

probably subjective, the main differences would be the added line and the function call statement (as opposed to a function call expression)

QA ✅

• ~/.enso/credentials exists and contains the correct keys
• ~/.enso/credentials is deleted when signing out

I'm assuming testing isn't strictly necessary on other OSes as this is just modifying existing functionality - but of course it doesn't hurt to test on other platforms
