Quote branch name in delete command

[gabrielmaldi]

Fixes error when deleting, for example, a branch with parentheses () in its name:

git branch -D my/branch(test)
/bin/sh: -c: line 0: syntax error near unexpected token `('
/bin/sh: -c: line 0: `git branch -D my/branch(test)'
node:internal/errors:856
  const err = new Error(message);
              ^

Error: Command failed: git branch -D my/branch(test)
/bin/sh: -c: line 0: syntax error near unexpected token `('
/bin/sh: -c: line 0: `git branch -D my/branch(test)'
