Auto merge of #79329 - camelid:int-lit-suffix-error, r=davidtwco

Update error to reflect that integer literals can have float suffixes

For example, `1` is parsed as an integer literal, but it can be turned
into a float with the suffix `f32`. Now the error calls them "numeric
literals" and notes that you can add a float suffix since they can be
either integers or floats.
