Hi @anwesh,
We try to update the premade files for each QIIME 2 release, but this may not always be the case. The provenance information contained within the downloadable premade files will tell you which version of SILVA was used to generate the database. Just drag and drop into QIIME 2 View, and click on Provenance tab.
This is the beauty of RESCRIPt, the information on how the reference database was made will be included in your analysis. Note the version information in the screenshot below when I used QIIME 2 view on your 3_taxa_plots_202405.qzv file.
Also I just want to point out some of my thoughts here. It does focus a little on UNITE, but the general perspective still applies.
