Adding the Hashicorp variant of the Business Source License 1.1

[ringods]

Fixes: #67

Hashicorp relicensed their product offering to the Business Source License 1.1

https://github.com/search?q=org%3Ahashicorp+%22Business+Source+License+1.1%22+language%3AText&type=code&l=Text

The LICENSE files installed in the repositories have a Hashicorp specific preamble, for instance:\

https://github.com/hashicorp/terraform/blob/ec0ecca1a6eef4bd90138de064b9e54b668622ac/LICENSE#L4-L47

I added a variant to the Business Source License assets folder matching the Hashicorp style LICENSE files starting from line 51.

https://github.com/hashicorp/terraform/blob/ec0ecca1a6eef4bd90138de064b9e54b668622ac/LICENSE#L4-L47

With this variant in place, the licenses are properly matched:

$ cd v2
$ wget https://raw.githubusercontent.com/hashicorp/terraform/refs/heads/main/LICENSE -O LICENSE-tf.txt
$ go run tools/identify_license/identify_license.go LICENSE-tf.txt

/Users/ringods/Projects/pulumi/licenseclassifier/v2/LICENSE-vault.txt Business-Source-License-1.1 (variant: hashicorp.txt, confidence: 1, start: 51, end: 92)

How can I add & run tests from v2/scenarios?
