CTHUB - GER Geographic names check

**Describe the task**
`City` should have real geographic names. To do so, the dataset should be checked against a list of community names in BC. If the name is not in that list, a user should get a warning. They can proceed to upload regardless or they can work on their excel file to fix it before uploading.

**Purpose**
Normalizes `City` information to be typo-free.

**Acceptance Criteria**
- [x] User should get a warning with a list of names and locations by index of cells that are not in the list of community names in BC.
- [x] User should be able to ignore the warning and upload the file.

**Additional context**
