The hcp-sbom provisioner is a provisioner that acts essentially like a
download-only file provisioner, which also verifies the file downloaded
is a SPDX/CycloneDX JSON-encoded SBOM file, and sets up its upload to
HCP Packer later on.
# Description
The output of the example on [uuidv4 Function](https://developer.hashicorp.com/packer/docs/templates/hcl_templates/functions/uuid/uuidv4) is not a valid RFC compliant UUIDv4. It indicates the usage of the `uuidv4()` function and outputs `b5ee72a3-54dd-c4b8-551c-4bdc0204cedb` which is not a valid UUIDv4.
I've corrected the example to output a UUIDv4 conforming to the RFC as such `xxxxxxxx-xxxx-4xxx-Nxxx-xxxxxxxxxxxx`, where:
- The 13th character is always `4` (indicating version 4).
- The 17th character must be either `8`, `9`, `a`, or `b` (indicating the first character of the variant).

Replaces the old UUID output with a valid RFC compliant UUIDv4.

# Misc.
To make sure this wasn't an issue with the `uuidv4()` function within Hashicorp's [packer](https://github.com/hashicorp/packer) I tested the function in the following way:
### Command executed:
```ps
> .\packer.exe inspect .\uuid.pkr.hcl
```
### Contents of the _uuid.pkr.hcl_ file:
```hcl
locals {
uuid_0 = uuidv4()
uuid_1 = uuidv4()
uuid_2 = uuidv4()
uuid_3 = uuidv4()
uuid_4 = uuidv4()
uuid_5 = uuidv4()
uuid_6 = uuidv4()
uuid_7 = uuidv4()
uuid_8 = uuidv4()
uuid_9 = uuidv4()
}
```
### Output:
```ps
