[branch-2.1][fix](default value) Avoid default precision value of 0 for default expressions during deserialization (#40806)

Browse Source 
pick  (#40671)

This PR fixes the issue where the precision of default value expressions
was incorrectly set to `0` during deserialization. The `gsonPostProcess`
method no longer assigns a default precision of `0` if the precision is
not provided. Additionally, logic has been added to ensure that
expressions without precision do not incorrectly apply a precision of
`0`.
