lemur::align_harmony causes an error with recent versions of harmony

Reproducible example: see https://github.com/Bioconductor/CSAMA-labs/tree/devel/multicond-scRNA-lemur code chunk "align-lemur-model".

```
fit2 <- lemur(sce, design = ~ stim, n_embedding = 30, verbose = FALSE)
fit2 <- align_harmony(fit2, verbose = FALSE)
```
**Error in `check_legacy_args()`:
! Argument max.iter is unhandled. Please refer to the documentation for the valid harmony options!**

Suggestions:

1.) preferentially: bug fix in the Bioconductor release of lemur, in time for CSAMA, second-best: a fix within the above lab qmd lab itself
2.) fix for next Bioconductor release, incl unit & integration test to pick up such problems automatically in the future

Thank you and kind regards
