BI-2267 Trim trailing white space on breeding method file uploads

Description

When importing germplasm, if there was a trailing blank in a breeding method value, then the system was generating the table error Invalid breeding method.

This fix removes any leading and trailing spaces in the imported breeding method values.

Dependencies

Please include any dependencies to other code branches, testing configurations, scripts to be run, etc.

Testing

1. Import a germplasm file with a trailing blanks in some of the breeding method field. You can use ABC_germplasm_2024-08-02_06-20-46+0000import.xlsx which has trailing blanks in every breeding method with the value "unknown "

EXPECTED RESULT
There should be no Table Error Invalid breeding method
