[wrynose][PATCH 1/4] spdx30_tasks: Fix duplicated revision in Git PURLs

[Stefano Tondo <stondo@gmail.com>]

From: KAZUYOSHI AKIYAMA (秋山 和慶) <kazuyoshi_akiyama@jp.honda>

_generate_git_purl() generates invalid PURLs of the form
`pkg:github/<owner>/<repo>@<rev>@<rev>`.
purl-spec only allows a single `@<rev>`.

oe.spdx_common.fetch_data_to_uri() already appends "@<rev>" to the
download location, and urlparse() leaves that suffix in parsed.path.
Therefore, the parsed repository name(`{repo}`) includes `@<rev>`.
So, need to strip the revision suffix before splitting out
the owner(`{owner}`) and the repository name(`{repo}`).

While here, replace str.replace(".git", "") with str.removesuffix() so
repository names that contain ".git" elsewhere are preserved.
