Mozilla Public License 2.0 (MPL-2.0) is detected as "non-standard"

When querying license information from https://api.deps.dev/v3alpha/systems/maven/packages/org.verapdf:feature-reporting/versions/1.28.2, the MPL 2.0 license is detected as "non-standard", even though it's in the list of SPDX Licenses: https://spdx.org/licenses/

There are probably a few other licenses in that list where deps.dev would report "non-standard".
