Fixes #27605: inline math blocks can't be preceeded/followed by alphanumerical characters (#30175) (#30250) 
Backport #30175 by @jmlt2002

- Inline math blocks couldn't be preceeded or succeeded by
alphanumerical characters due to changes introduced in PR #21171.
Removed the condition that caused this (precedingCharacter condition)
and added a new exit condition of the for-loop that checks if a specific
'$' was escaped using '\' so that the math expression can be rendered as
intended.
- Additionally this PR fixes another bug where math blocks of the type
'$xyz$abc$' where the dollar sign was not escaped by the user, generated
an error (shown in the screenshots below)
- Altered the tests to accomodate for the changes

Former behaviour (from try.gitea.io):

Fixed behaviour (from my local build):

(Edit) Source code for the README.md file:

a$xa$ $xa$a 1$xb$ $xb$1

$a a$b b$

a$b $a a$b b$
