Fix S2629 FP: Allow concatenation of constants

[hankovich]

Description

S2629: Don't use string concatenation in logging message templates.

Repro steps

            Logger.LogError(e,
                "Cannot initialize storage, will retry in {Span}. " +
                "Executed {ExecutedCount} migrations of {TotalCount}. Failed on `{Name}`. Data: {Data}",
                RetryTimeSpan,
                index,
                migrationScripts.Count,
                migrationName,
                e.Data);

Expected behavior

No warnings are reported. Since I concatenate constant literals

Actual behavior

S2629 is reported.
