fix: regions, test buckets

[sa7mon]

Summary

Update regions, region checks, and test buckets. Temporarily disable Dreamhost tests as scanning is broken (#456).

Region Changes

• DigitalOcean: added ric1
• Linode: added fr-par-13 and us-iad-18
• Scaleway: added it-mil
• Wasabi: added us-west-2

Regioncheck Changes

• Scaleway: replaced the fragile regex scrape of a docs-content markdown file on GitHub with the official Scaleway product catalog API
• DigitalOcean: updated the row-header match from Spaces to Spaces Standard Storage to follow a change in product availability matrix
• Linode: pointed the scraper at Akamai's new endpoint-types docs page and updated the table selectors accordingly

Test Fixes

• Replaced test buckets that no longer exist or whose contents changed (DigitalOcean, GCP, Wasabi) and updated expected object counts and permissions
• Temporarily disabled Dreamhost tests pending a fix (see bug: [dreamhost] scanning broken #456)
• Added a negative BucketExists test for Wasabi
• Made Test_StorageProvider_Enum fail fast with a clear message when a bucket unexpectedly doesn't exist, and fixed an assertion-ordering issue in Test_StorageProvider_Scan where the scan ran before the existence error was checked
• Discovered bug: [wasabi] throws error if bucket owned by inactive account #455 while fixing Wasabi tests
