Add *.tsbuildinfo to .gitignore of examples that use typescript

[AleksaC]

I added *.tsbuildinfo to gitignores of examples that use typescript and don't already have it. By use typescript I mean have tsconfig somewhere in their directory tree.

I used the following script to update the files:

#!/bin/bash

set -eou pipefail

cd examples
examples=`git ls-files . | grep tsconfig | xargs dirname | grep -v "/"`

for example in $examples; do
    if ! grep -q tsbuildinfo $example/.gitignore; then
        gitignore="$example/.gitignore"
        echo $gitignore
        tail -c1 $gitignore | read -r _ || echo >> $gitignore
        echo -e "\n# typescript\n*.tsbuildinfo" >> $gitignore
    fi
done
