Update phpbench baseline

[staabm]

benchmarked the 2 biggestest offenders by phpbench in hyperfine

2.1.x@e905481:

➜  phpstan-src git:(2.1.x) ✗ hyperfine 'bin/phpstan analyze bug-10979.php' 'bin/phpstan analyze bug-4308.php' --warmup=2 -i
Benchmark 1: bin/phpstan analyze bug-10979.php
  Time (mean ± σ):      1.783 s ±  0.005 s    [User: 1.376 s, System: 0.348 s]
  Range (min … max):    1.776 s …  1.790 s    10 runs
 
Benchmark 2: bin/phpstan analyze bug-4308.php
  Time (mean ± σ):      1.158 s ±  0.002 s    [User: 0.798 s, System: 0.341 s]
  Range (min … max):    1.155 s …  1.164 s    10 runs

and on 2.1.49:

➜  phpstan-src git:(a25e50956f) ✗ hyperfine 'bin/phpstan analyze bug-10979.php' 'bin/phpstan analyze bug-4308.php' --warmup=2 -i
Benchmark 1: bin/phpstan analyze bug-10979.php
  Time (mean ± σ):      1.695 s ±  0.004 s    [User: 1.235 s, System: 0.354 s]
  Range (min … max):    1.687 s …  1.703 s    10 runs
 
Benchmark 2: bin/phpstan analyze bug-4308.php
  Time (mean ± σ):      1.166 s ±  0.004 s    [User: 0.808 s, System: 0.346 s]
  Range (min … max):    1.159 s …  1.170 s    10 runs

in bug-10979.php we lost 80ms, which I think is good enough. will update the baseline
