Compare View, Executor Comparison: New Benchmarks/Benchmark Suites

[smarr]

A new benchmark suite is indicated in the navigation, but then doesn't seem to be in the actual comparison. Here for the example of the interpreter suite:

• https://rebench.dev/TruffleSOM/compare/14c1f7dfcea7165bf7cdc4e235df0570d29603cc..4018bc1468870fa29e31419276b70f8495e188f5#exe-comparisons
• https://rebench.dev/som-rs/compare/17c377dc902cf8e2b742a0dff0c3a0d29be88294..21089dfeaa4fec34024c8994a551d3aba65c3cc7#exe-comparisons

Since this does not rely on the baseline commit version, the executor comparison should really include it.
This is super useful when introducing a new suite, and possibly individual benchmarks.
And since the executor comparison might even be the main focus, it seems like a bug not having the comparison show up here.
