Fix failures from #75169

Minor re-tag due to version number / changelog commit:
coccinelle/coccinelle@e84d3dd...25e7cee

pcre is a build/runtime dependency:

• Build:

  checking for libpcre... yes
  configure: configuring package pcre
  

• Test:

  dyld: Library not loaded: /usr/local/opt/pcre/lib/libpcre.1.dylib
    Referenced from: /usr/local/Cellar/coccinelle/1.1.0_1/bin/spatch
    Reason: image not found
  Error: coccinelle: failed
  

pkg-config is optional (fallback is used if unavailable), but might as well add since recommended:

pkg-config (optional, but strongly recommended)

Can this use pcre2?

[cho-m]

I haven't tried. I mainly based on other formula that use both ocaml and pcre:

haxe.rb
37:  depends_on "pcre"

comby.rb
22:  depends_on "pcre"

semgrep.rb
30:  depends_on "pcre"

Looking at discussion in pcre-ocaml mmottl/pcre-ocaml#10 it sounds like there was no plan to support pcre2 unless someone else contributed it.
