Conflicting bs_theme version requirements

The FIXME at the end of the following quote was written because of the issue described thereafter.

CougarStats/R/multipleLinearRegression.R

Lines 32 to 55 in c5a5a89

	MLRMainPanelUI <- function(id) {
	ns <- NS(id)
	navbarPage(title = NULL,
	tabPanel(title = "Data Import",
	import_ui(id = ns("dataImport"), from = c("file", "copypaste"))),
	tabPanel(title = "MLR",
	fluidPage(
	fluidRow(uiOutput(ns("linearModelEquations"))),
	fluidRow(verbatimTextOutput(ns("linearModelSummary"))),
	## NOTE: Ashok didn't ask for these, but they're here.

	fluidRow(verbatimTextOutput(ns("linearModelANOVA")))),
	tabPanel(title = "Diagnostics",

	tabPanel(title = "Diagnostic Plots"),
	## FIXME: if the version is 5 then import_ui will break! NOTE:
	## write a support request on the Posit Shiny subform asking for
	## advice. I don't understand why this is this way.
	theme = bs_theme(version = 4))
	}

If this version is set to 5, or unset (and defaulting to 5), then an error will be produced complaining about a bootstrap component requiring version five. Oddly, it seems to be the import_ui module which requires bootstrap 5, and yet giving it bootstrap 5 causes an issue.

Reproduction of the issue to better describe it is needed.
