🤦‍♀️ Dot between build ID and commit on Azure Pipelines (#113)

#### Summary:
Need a "." between build number and commit, not a plus

#### Motivation:
Use non-tagged templates built by Azure

##### References (optional):
purduesigbots/pros-cli#66
purduesigbots/pros-cli#64

#### Test Plan:
- [x] Can fetch/use template built locally
- [x] Can fetch/use template built on Azure


#### Commits:
* dot between build number and commit

* Dots are better in general
