fix(protractor): update rules_webtesting patch to include additional windows fixes (#1140)

Cannot update to latest rules_webtesting commit as we need to depend on the release package which does not have a rules_go dependency. This patch can be removed once we update to the next rules_webtesting release.

+Subject: [PATCH] web test not launching on windows if shell toolchain path
+ contains whitespace (#389)
+
+The windows launcher code does currently break if the path to the bash binary contains
+a whitespace. This is common on windows where programs are stored under `C:\Program Files`.
+
+e.g.
+
+```
+:run
+C:/Program Files/msys2/usr/bin/bash.exe -c "!run_script!"
+```
+
+The path needs to be quoted so that it won't be incorrectly picked up as two separate commands. Resulting in an
+exception like:
+
+```
+'C:/Program' is not recognized as an internal or external command,
+operable program or batch file.
