Lightning: fix incorrect parse tidb release version

[whitekeepwork]

What problem does this PR solve?

this PR resolved parallel import conflict caused by unexpected output from tidb_version() return.

Issue Number: close #37007

Problem Summary:
tidb version number cause parallel import conflict records

What is changed and how it works?

In the FetchVersion function, I added a precheck for querying the results of the tidb_version() function before it returns.
If querying results didn't match a pattern of Release Version: v, then there are no valid release versions that will be parsed by ParseServerInfo. it should turn into fall back and return the result from select version()
