fix: derive_param_tte() fails for dplyr 1.1.0

Closes #1962
Linked PR: #1962
What happened?

If dlpyr 1.1.0 is used, some tests for derive_param_tte() fail. They pass for dplyr 1.0.5 (minimum version required by admiraldev) and also for dplyr 1.1.1.

In derive_param_tte()

full_join(
  mutate(by_groups, temp_dummy = 1),
  mutate(source_datasets[[i]], temp_dummy = 1),
  by = "temp_dummy",
  relationship = "many-to-many"
) %>%
select(-temp_dummy)

should be replaced by

crossing(
  by_groups,
  source_datasets[[i]]
)

We fisnished this one in #1997. Thanks again for trying to fix this - I still recommend running through the Onboarding issue to get some more experience on how we operate. - #1839

This test issue might be a good one to jump on - #1466
