[Bugfix]: Correct index population on provision-atlas.sh

[Jibola]

Summary

Found in provision-atlas.sh -- The for file in $TARGET_DIR/indexes/*.json loop now removes the quotes as it will expand the glob as one expression "$TARGET_DIR/indexes/*.json" --> "$TARGET_DIR/indexes/x.json, $TARGET_DIR/indexes/y.json" rather than do individual loop iterations.

Incorrect Behavior

for file in "$TARGET_DIR/indexes/*.json"; do
    echo $file "DELIMIT"
done

outputs,

>> echo $TARGET_DIR/indexes/x.json $TARGET_DIR/indexes/y.json DELIMIT

Correct Behavior

for file in $TARGET_DIR/indexes/*.json; do
    echo $file "DELIMIT"
done

outputs,

>> echo $TARGET_DIR/indexes/x.json DELIMIT
>> echo $TARGET_DIR/indexes/y.json DELIMIT

Test for correctness

Check #7 as it implements the correction. Documenting in its own PR for posterity.
