Fix code scanning alert no. 370: Useless regular-expression character…

… escape (elastic#198264)

Fixes
[https://github.com/elastic/kibana/security/code-scanning/370](https://github.com/elastic/kibana/security/code-scanning/370)

To fix the problem, we need to remove the unnecessary escape sequence
`\-` from the regular expression on line 32. This will not change the
functionality of the code but will make the regular expression clearer
and more maintainable.

- In general terms, we need to ensure that only necessary escape
sequences are used in regular expressions.
- Specifically, we will update the regular expression on line 32 to
remove the unnecessary escape sequence.
- The change will be made in the file
`x-pack/plugins/session_view/public/methods/index.tsx`.
