docs: move Registration to the top; minor reword r/8281

When trying to follow Review documentation, I got tripped up on the
“Gerrit setup” section that was asking about SSH keys since I hadn’t yet
gotten an account setup but the registration setion was near the bottom
of the document despite being a requirement for setting up Gerrit.

Included words specifying SSO, specifies that the TVL account is an
alternative method, & commit→patch since you send a patch with the
commit.

+## Registration
+
+The preferred method of contributions & review is done via Gerrit.

+TVL’s Gerrit supports single sign-on (SSO) using a GitHub, StackOverflow or
+GitLab.com account.
+
+Additionally if you want prefer not to use an SSO option or wish to have a
+backup authentication strategy in the event of downed server or a keycloak
+issue (recommended), you can create a TVL-specific LDAP account on the Gerrit
+instance by following these instructions:
+
+1. Be a member of `#tvl` on [hackint][].
+2. Clone the depot locally (via `git clone "https://cl.tvl.fyi/depot"`).
+3. Create a user entry in our LDAP server in [ops/users][ops-users].
