chore: Update empty transaction table copy (#88331)

Empty table with the message "No transactions found" is a bit confusing
when the table says there are 6 transactions for this release. The
filter for "Failed transactions" is much smaller than the "Not found"
text. This updates the text to indicate there is a filter being applied.
