Subject: [PATCH] PG18 - Strip decimal fractions from actual rows counts in
 normalize.sed (#8041)

Fixes #8040

- Custom Scan (Citus Adaptive) (actual rows=0 loops=1)
+ Custom Scan (Citus Adaptive) (actual rows=0.00 loops=1)
```


Add a normalization rule to the pg_regress `normalize.sed` script that
strips any trailing decimal fraction from actual rows= counts (e.g.
turning `actual rows=0.00` into `actual rows=0`). This silences noise
diffs introduced by the new PostgreSQL 18 beta’s planner output.
