Strava provider work wrong

[SxYxuse]

Hi,

The first small fix to do it's in the doc -> you should pass the refreshToken instead of accessToken in the refresh method

Then when the authorization url is created the scopes should have a , between them instead of spacing. Because currently everytime we redirect to the Strava Promp we need to grant access instead of doing it automatically.

Must look like this : scopes=activity:read_all,read

Thanks

Fixed the typo. Looks like all the providers' doc had that issue.

As for scopes, that's not compliant with the spec so we'd probably want to remove the scope parameter. We don't follow semver so I could just remove it in the next minor release, but it technically "works" so I'm not sure yet.
