No --scopeType and --scopeType set to prefix gives different results when --include is set

[benoit74]

When an --include rule is passed to zimit, if --scopeType is not set, then only pages matching the include rule are fetched. When setting --scopeType to prefix, all URLs matching the include rule or the prefix of --url are fetched.

This contradicts the fact that by default --scopeType is prefix.

To be investigated.

maybe just defaulting to prefix

parser.add_argument(
    "--scopeType",
    help="A predefined scope of the crawl...",
    choices=["page", "page-spa", "prefix", "host", "domain", "any", "custom"],
    default="prefix",
)

The prefix default value should already be the case in Browsertrix crawler (where this argument is used). So question is more to investigate if Browsertrix crawler default has changed, if this is intentional or a bug, if we should update our documentation or if we should pass our own default (which we prefer to avoid so that we mostly stay in-line with Browsertrix behavior).
