Using the relative path instead of the absolute path in portable mode for "content"

[enjoying-codes]

It tested & works to change the absolute path of "content" in portable\config file after initial indexing.

For example,

<path recursive="1">D:/GoldenDict-ng/content</path>
<hunspell dictionariesPath="D:/GoldenDict-ng/content/morphology"/>

to

<path recursive="1">./content</path>
<hunspell dictionariesPath="./content/morphology"/>

It's helpful for launching the goldendict.exe in any path in portable mode without additional setting.

"v25.02.0-Release.e895b18c" solved this problem in other way: "fix: default content directory in portable mode in #1872"

The path on the first line is grey, which is automatically fetched by program itself at each launch and cannot be removed.
In future, the relative path "./" could be considered if in case of conflict.
