The default brew-installed version of Tcl is now 9.0. The release page lists a few incompatibilities: https://www.tcl-lang.org/software/tcltk/9.0.html. For now, I am pinning the build to Tcl 8, but it would be good to know if our tiny bit of Tcl code is compatible with 9.0, and if/when it will be desirable to update the Soar build to use 9.0.

Find correct brew-installed Tcl
dde2533 
Revert the last commit, which didn't help find the correct Tcl installation.

Since the default brew-installed version of Tcl is now 9.0, the runner image
installs Tcl 8 using the prefix `tcl-tk@8`. Try both prefixes and use the one
that works.

Opened #524, as well, to consider whether we need to support Tcl 9 in the
future.

Note that running Tcl 9's tclsh on our test Tcl script, after compiling Soar against Tcl 8, gives a segfault.
