…st (#2371) In #2356 a session would be upgraded to v2 refresh tokens based on the number of requests for that session. If you set a percentage value of 10% and there's 100 refresh token requests per session, all sessions would be upgraded within 1 day. This is rectified here by converting the session ID to a value in the `[0, 100)` range making sure that a random selection of sessions would be upgraded consistently.

If the refresh token algorithm version is set to 2, only new sessions would be using these. By setting
GOTRUE_SECURITY_REFRESH_TOKEN_UPGRADE_PERCENTAGEto a value between 0 and 100 inclusive, on the next refresh token request a session using a v1 refresh token will switch to using a v2 refresh token.The percentage is to allow for gradual rollout, as the upgrade step can result in some concurrent refreshes to terminate the session early.
