RSpec one-liner examples (e.g., `it { is_expected.not_to be_nil }`)
generate descriptions after execution. Updated formatter to capture
the final description in `example_finished` instead of relying on
the incomplete description at `example_started`.

## Why?
Span names and full descriptions for RSpec one-liner syntax (like `it {
is_expected.not_to be_nil }`) were incorrectly showing file locations
instead of the matcher-generated descriptions. This made tracing output
less useful for tests using the concise one-liner syntax.
## How?
RSpec generates descriptions for one-liner examples after execution,
when the matcher runs. The formatter was capturing `description` and
`full_description` at `example_started` time, before these values were
populated.
The fix updates both the span name and `full_description` attribute in
the `example_finished` callback, after RSpec has generated the proper
description from the matcher. This ensures accurate span names and
descriptions for both one-liner and traditional examples.
We need to point Intercom's Gemfile to this repo so that we get those
updates without waiting for the upstream repo to accept them.

@chrisholmes may I ask for a review please? |
I'm away from computer so I can't test it myself, but the change is simple enough and it makes sense to me. |

Please review at your leisure. With your approval I will merge this PR. |
