fix #25024

[fxcoudert]

No, this should not hardcode a path.

[fxcoudert]

Again, no. This is not acceptable.

latex2html depands on a TeX system (TeXLive), on macOS, it's MacTex (the only one). But it's in homebrew-cask instead of homebrew-core, we can't draw the dependence in formula. And this package is pure code, no need to bottle at the very start.

Unless include mactex into brew-core, there is no way to elegantly fix it. Now latex2html is broken all the way, if it's not acceptable, please remove this formula rather then leaving a trap.

We welcome a fix that follows the rules of homebrew formulas.

There is a configure && make process, and the files produced are system-dependent (which we know because the bottles on different macOS versions have different checksums). So it should be bottled.

Miktex can be installed on macOS. TeXLive can be installed in non-default paths. We need to consider these possibilities.

Confirmed by installing locally that software works fine by setting l2hconf.pm manually. That latex2html cannot work by autodetecting installed latex binaries when they are in PATH is their bug to fix, it's actually been reported but the project appears inactive: latex2html/latex2html#22
