Fix inconsistent test outcomes in LogTransformDataCheck tests

[ParthivNaresh]

Some of the tests for LogTransformDataCheck don't create the sample data consistently as expected.

test_target_distribution_data_check_unsupported_target_type ends up creating a lognormal target set (due to a low random sample count) instead of a normal one for parameters integer and double. Here is an example error, as well as here:

(test_target_distribution_data_check_unsupported_target_type[double])
{'actions': [{'code': 'TRANSFORM_TARGET',
              'metadata': {'column': None,
                           'is_target': True,
                           'transformation_strategy': 'lognormal'}}],
 'errors': [],
 'warnings': [{'code': 'TARGET_LOGNORMAL_DISTRIBUTION',
               'data_check_name': 'TargetDistributionDataCheck',
               'details': {'shapiro-statistic/pvalue': '0.972/0.035'},
               'level': 'warning',
               'message': 'Target may have a lognormal distribution.'}]} != {'actions': [], 'errors': [], 'warnings': []}

test_target_distribution_data_check_warning_action runs into an issue with rounding of the Shapiro statistic:

(test_target_distribution_data_check_warning_action[very_lognormal-positive])
{'actions': [{'code': 'TRANSFORM_TARGET',
              'metadata': {'column': None,
                           'is_target': True,
                           'transformation_strategy': 'lognormal'}}],
 'errors': [],
 'warnings': [{'code': 'TARGET_LOGNORMAL_DISTRIBUTION',
               'data_check_name': 'TargetDistributionDataCheck',
               'details': {'shapiro-statistic/pvalue': '0.793/0.0'},
               'level': 'warning',
               'message': 'Target may have a lognormal distribution.'}]} != {'actions': [{'code': 'TRANSFORM_TARGET',
              'metadata': {'column': None,
                           'is_target': True,
                           'transformation_strategy': 'lognormal'}}],
 'errors': [],
 'warnings': [{'code': 'TARGET_LOGNORMAL_DISTRIBUTION',
               'data_check_name': 'TargetDistributionDataCheck',
               'details': {'shapiro-statistic/pvalue': '0.794/0.0'},
               'level': 'warning',
               'message': 'Target may have a lognormal distribution.'}]}

@ParthivNaresh Is this a dup of #2581 ?
