west: runners: openocd: Fix version format regression

Change OpenOCD version regex to be compatible again with format strings
not having a space or newline immediately after the version nr.

Modified regex has been verified with the strings listed below.

Ubuntu:
"Open On-Chip Debugger 0.11.0"

ADI:
"Open On-Chip Debugger (Analog Devices 0.12.0-1.1.1)  OpenOCD 0.12.0 (2024-
08-27-17:25)"

Zephyr SDK:
"Open On-Chip Debugger 0.11.0+dev-00728-gb6f95a16c (2024-02-17-23:51)"

Infineon:
"Open On-Chip Debugger 0.12.0+dev-5.2.1.3248 (2024-08-08-17:29)"

Espressif:
"Open On-Chip Debugger v0.12.0-esp32-20240318 (2024-03-18-18:25)"
