Symbol "\" in messages when use code or link in markdown

Hi, I think I found small bug)

When I use `format: markdown`, use string with letter "_" as first symbol (folder name in my situation) and as result different cases:
- "_Some text" as normal text - ok
- `_Some text` with "'" symbol around - as result "\_Some text" in Telegram message I see symbol "\" as first
- [_Some text](some link) - "\" symbol too in Telegram, as result "\_Some text"

Reproduce the issue with format: markdown using the three underscore examples in the report, then trace the action's message-formatting and Telegram-send entry points. Done means inline code and linked text no longer produce a leading backslash in the delivered Telegram message, while the plain-text case remains unchanged.
