Addresses reverse dep check for get_joined_sub_data(...) using left_join(..., relationship = "many-to-many" )

This fixes warnings with a version of dplyr that seems to warn more aggressively. I wonder why plain dplyr doesn't trigger a warning here.

Wild guess: could this function be made more efficient with dplyr's new rolling joins?

• Place Closes #<insert_issue_number> into the beginning of your Pull Request Title (Use Edit button in top-right if you need to update)
• Code is formatted according to the tidyverse style guide. Run styler::style_file() to style R and Rmd files
• Updated relevant unit tests or have written new unit tests, which should consider realistic data scenarios and edge cases, e.g. empty datasets, errors, boundary cases etc. - See Unit Test Guide
• If you removed/replaced any function and/or function parameters, did you fully follow the deprecation guidance?
• Review the Cheat Sheet. Make any required updates to it by editing the file inst/cheatsheet/admiral_cheatsheet.pptx and re-upload a PDF and a PNG version of it to the same folder. (The PNG version can be created by taking a screenshot of the PDF version.)
• Update to all relevant roxygen headers and examples, including keywords and families. Refer to the categorization of functions to tag appropriate keyword/family.
• Run devtools::document() so all .Rd files in the man folder and the NAMESPACE file in the project root are updated appropriately
• Address any updates needed for vignettes and/or templates
• Update NEWS.md under the header # admiral (development version) if the changes pertain to a user-facing function (i.e. it has an @export tag) or documentation aimed at users (rather than developers). A Developer Notes section is available in NEWS.md for tracking developer-facing issues.
• Build admiral site pkgdown::build_site() and check that all affected examples are displayed correctly and that all new functions occur on the "Reference" page.
• Address or fix all lintr warnings and errors - lintr::lint_package()
• Run R CMD check locally and address all errors and warnings - devtools::check()
• Link the issue in the Development Section on the right hand side.
• Address all merge conflicts and resolve appropriately
• Pat yourself on the back for a job well done! Much love to your accomplishment!
