chore(generator-cli): remove .fern/replay.yml from REPLAY_FERNIGNORE_ENTRIES

[tstanmay13]

Description

Removes .fern/replay.yml from the list of files that fern replay init adds to .fernignore.

Changes Made

• Removed .fern/replay.yml from the REPLAY_FERNIGNORE_ENTRIES constant in fernignore.ts, reducing it from 3 entries to 2 (.fern/replay.lock and .gitattributes)
• Updated the corresponding test assertions in replay-pure.test.ts

Human Review Checklist

• Confirm .fern/replay.yml no longer needs to be preserved across generations (i.e., it's fine for fern generate to overwrite it)
• Verify no downstream consumers (e.g., fiddle server-side) explicitly depend on .fern/replay.yml being in the fernignore entries list

Testing

• Unit tests updated
• Lint (biome check) passes
