Including the changes to use F10.6 precision for domain_centre

[Claudio Sanchez (mo-claudiosanchez)]

PR Summary

Sci/Tech Reviewer: Ricky Wong (@mo-rickywong)
Code Reviewer: mo-marqh

This PR is made to write the domain_centre variable in the mesh's "constructor_inputs" with higher truncation (from 2 to 6 decimals).

See issue #433

Code Quality Checklist

• I have performed a self-review of my own code
• My code follows the project's style guidelines
• Comments have been included that aid understanding and enhance the readability of the code
• My changes generate no new warnings
• All automated checks in the CI pipeline have completed successfully

Testing

• I have tested this change locally, using the LFRic Core rose-stem suite
• If required (e.g. API changes) I have also run the LFRic Apps test suite using this branch
• If any tests fail (rose-stem or CI) the reason is understood and acceptable (e.g. kgo changes)
• I have added tests to cover new functionality as appropriate (e.g. system tests, unit tests, etc.)
• Any new tests have been assigned an appropriate amount of compute resource and have been allocated to an appropriate testing group (i.e. the developer tests are for jobs which use a small amount of compute resource and complete in a matter of minutes)

_The cylc-review of the rose stem testing is rose_stem_lfric_core/run1. All check_mesh_tools for LAMs fails as the branch outputs domain_centre with more zeroes. E.g.
