ref(replay): Rename replaysSampleRate to replaysSessionSampleRate

We wanted this config option to be a bit more specific in that it should be the sample rate for "session" replays (vs. on error samples). The previous name could be mistaken as a sample rate that affects both types of replays.

 Sampling allows you to control how much of your website's traffic will result in a Session Replay. There are two sample rates you can adjust to get the replays more relevant to your interests:
 
-- `replaysSampleRate` - The sample rate for replays that begin recording immediately and last the entirety of the user's session.
+- `replaysSessionSampleRate` - The sample rate for replays that begin recording immediately and last the entirety of the user's session.
 - `replaysOnErrorSampleRate` - The sample rate for replays that are recorded when an error happens. This type of replay will record up to a minute of events prior to the error and continue recording until the session ends.
 
-Sampling occurs when the session is first started. `replaysSampleRate` is evaluated first. If it is sampled, then the replay recording begins. Otherwise, `replaysOnErrorSampleRate` is evaluated and if it is sampled, the integration will begin buffering the replay and will only upload a replay to Sentry when an error occurs. The remainder of the replay will behave similarly to a whole-session replay.
