fix(test): increase timeout for network-dependent purlExists tests (#15)

* fix(test): increase timeout for network-dependent purlExists tests

The conda and docker purlExists tests make real HTTP requests to external
registries. The conda test was timing out on CI at the default 10s limit.
Increase timeout to 30s for both network-calling tests.

* fix(test): reduce timeout to 15s
